Title: Conflict with caching plugin Last modified: August 24, 2016 --- # Conflict with caching plugin * Resolved [barkingbird](https://wordpress.org/support/users/barkingbird/) * (@barkingbird) * [11 years, 2 months ago](https://wordpress.org/support/topic/conflict-with-caching-plugin/) * I recently switched to ZenCache for a caching solution but lost mobile detect functionality. When I disable ZenCache, mobile detect works. * Can you recommend a caching solution that doesn’t conflict with Mobile Detect? * My htaccess file: ********************************************** # Use PHP54 Single php.ini as default AddHandler application/x-httpd-php54s .php * AddOutputFilterByType DEFLATE text/plain text/html application/x-httpd-php-source AddOutputFilterByType DEFLATE text/xml application/xml application/xhtml+xml application/xml-dtd AddOutputFilterByType DEFLATE application/rdf+xml application/rss+xml application/atom+xml image/svg +xml AddOutputFilterByType DEFLATE text/css text/javascript application/javascript application/x-javascript AddOutputFilterByType DEFLATE font/truetype application/ x-font-ttf font/opentype application/x-font-otf * # BEGIN WordPress RewriteEngine On RewriteBase / RewriteRule ^index\.php$ – [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME}!- d RewriteRule . /index.php [L] * # END WordPress * *************************************** I moved the coding between and including BEGIN WordPress and END WordPress to the the top just above the IfModule mod_deflate code, but without success. * [https://wordpress.org/plugins/addfunc-mobile-detect/](https://wordpress.org/plugins/addfunc-mobile-detect/) Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Author [Joe Rhoney](https://wordpress.org/support/users/joerhoney/) * (@joerhoney) * [11 years, 2 months ago](https://wordpress.org/support/topic/conflict-with-caching-plugin/#post-6042803) * I don’t think your .htaccess is the problem. Especially if activating/deactivating ZenCache affects whether or not it’s working. You can remove your .htaccess code from this post, I don’t see anything that is likely to start the header too early( which is usually what interferes). Most likely it has to do with the way ZenCache works (based on what you said). I don’t have a lot of experience with caching yet, but I understand [WP Super Cache](https://wordpress.org/plugins/wp-super-cache/) is good. Have you tried that? * Plugin Author [Joe Rhoney](https://wordpress.org/support/users/joerhoney/) * (@joerhoney) * [11 years, 1 month ago](https://wordpress.org/support/topic/conflict-with-caching-plugin/#post-6042818) * Any luck with this, barkingbird? * Thread Starter [barkingbird](https://wordpress.org/support/users/barkingbird/) * (@barkingbird) * [11 years, 1 month ago](https://wordpress.org/support/topic/conflict-with-caching-plugin/#post-6042819) * I deactivated another plugin called Slimstat, which is a very good and robust analytics plugin, but which tends to have some serious conflict issues with other plugins. After deactivation, no problems. Thanks!

Thanks for letting me know. 🙂 * [@camu](https://wordpress.org/support/users/camu/), the only thing I can say on that is that what I’ve seen interfere with AddFunc Mobile Detect often, is when other developers include Mobile_Detect.php in their plugin/theme, but don’t wrap their include properly to see if the Mobile_Detect class already exists. For instance: * ``` if( !class_exists( 'Mobile_Detect' ) ) { // Include Mobile_Detect.php } ``` * So it could have something to do with that. Otherwise, it would be best to check with the Slimstat developers. * [Jason Crouse](https://wordpress.org/support/users/coolmann/) * (@coolmann) * [10 years, 11 months ago](https://wordpress.org/support/topic/conflict-with-caching-plugin/#post-6042834) * Okay thank you 😉 By the way, I am one of the developers! * Plugin Author [Joe Rhoney](https://wordpress.org/support/users/joerhoney/) * (@joerhoney) * [10 years, 8 months ago](https://wordpress.org/support/topic/conflict-with-caching-plugin/#post-6042852) * Ah!
