In some cases, the active WordPress theme may also cause compatibility issues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before starting the troubleshooting process, we strongly recommend creating a full backup of your website or performing these tests on a staging site.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tp-heading-1\">1. Identify the Conflicting Plugin or Theme<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Temporarily deactivate other plugins one by one and check whether the issue disappears after each change. Conflicts are most commonly caused by:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Similar third-party plugins with overlapping functionality<\/li>\n\n\n\n<li>Outdated plugins or themes<\/li>\n\n\n\n<li>Optimization or caching tools<\/li>\n\n\n\n<li>Media or image handling plugins<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If the issue disappears after disabling a specific plugin, you\u2019ve likely identified the conflicting plugin.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tp-heading-2\">2. Disable Overlapping Features<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Running multiple plugins that perform the same task can create conflicts. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Two thumbnail regeneration tools<\/li>\n\n\n\n<li>Multiple lazy load systems<\/li>\n\n\n\n<li>Multiple WebP conversion plugins<\/li>\n\n\n\n<li>Multiple image compression plugins<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Try disabling overlapping features in one of the plugins instead of disabling the entire plugin.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tp-heading-3\">3. Clear All Caches<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">After changing settings or disabling plugins, clear:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Website cache<\/li>\n\n\n\n<li>CDN cache<\/li>\n\n\n\n<li>Server\/VPS cache<\/li>\n\n\n\n<li>Browser cache<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Cached files can sometimes cause a conflict to appear unresolved, even after it has been resolved.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tp-heading-4\">4. Switch to a Default Theme<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Temporarily switch to a default WordPress theme, such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Twenty Twenty-Four<\/li>\n\n\n\n<li>Twenty Twenty-Three<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This helps determine whether the issue is caused by the active theme instead of another plugin.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tp-heading-5\">5. Enable Debug Logging<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Enable WordPress debug mode to capture PHP errors. Add this to your <code>wp-config.php<\/code> file:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>define( 'WP_DEBUG', true );\ndefine( 'WP_DEBUG_LOG', true );\ndefine( 'WP_DEBUG_DISPLAY', false );\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Then check: <code>\/wp-content\/debug.log<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This can help identify the exact plugin or function causing the conflict.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tp-heading-6\">6. Keep Everything Updated<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Make sure you are using:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The latest version of ThumbPress<\/li>\n\n\n\n<li>Updated plugins<\/li>\n\n\n\n<li>Updated theme<\/li>\n\n\n\n<li>Supported PHP version (recommended: PHP 8.1+)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Outdated software is a common cause of compatibility issues.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tp-heading-7\">7. Contact Support<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you still cannot identify the issue, contact ThumbPress <a href=\"https:\/\/help.pluggable.io\/new-ticket\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>support<\/strong><\/a> and provide:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>List of active plugins<\/li>\n\n\n\n<li>WordPress version<\/li>\n\n\n\n<li>PHP version<\/li>\n\n\n\n<li>Error messages or screenshots<\/li>\n\n\n\n<li>Steps to reproduce the conflict<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The more details you provide, the faster the issue can usually be resolved.<\/p>\n<div class='tp-content-after'><\/div>","protected":false},"author":6,"featured_media":0,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"nirohelp_product":[],"nirohelp_topic":[51],"class_list":["post-34990","nirohelp_doc","type-nirohelp_doc","status-publish","hentry","nirohelp_topic-troubleshooting"],"_links":{"self":[{"href":"https:\/\/thumbpress.co\/docs\/wp-json\/wp\/v2\/nirohelp_doc\/34990","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/thumbpress.co\/docs\/wp-json\/wp\/v2\/nirohelp_doc"}],"about":[{"href":"https:\/\/thumbpress.co\/docs\/wp-json\/wp\/v2\/types\/nirohelp_doc"}],"author":[{"embeddable":true,"href":"https:\/\/thumbpress.co\/docs\/wp-json\/wp\/v2\/users\/6"}],"wp:attachment":[{"href":"https:\/\/thumbpress.co\/docs\/wp-json\/wp\/v2\/media?parent=34990"}],"wp:term":[{"taxonomy":"nirohelp_product","embeddable":true,"href":"https:\/\/thumbpress.co\/docs\/wp-json\/wp\/v2\/nirohelp_product?post=34990"},{"taxonomy":"nirohelp_topic","embeddable":true,"href":"https:\/\/thumbpress.co\/docs\/wp-json\/wp\/v2\/nirohelp_topic?post=34990"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
