Title: conflict plugins error Last modified: July 29, 2022 --- # conflict plugins error * Resolved [chendaniel](https://wordpress.org/support/users/chendaniel/) * (@chendaniel) * [3 years, 10 months ago](https://wordpress.org/support/topic/conflict-plugins-error/) * Hello, Ive been struggling more then a week on solving an issue on my website. communicating with rapidload (Shakeeb) and another plugin called global gallery( Luca) I have this problem that when activating css optimzation The gallery doesnt function properly sometimes work and sometimes doesnt, on mobile version only. when clicking on the image it supposed to open in lightbox format, but sometimes it just loads the image during infinity time. rapidload claims its error in the css & js from the global gallery plugin so I passed forward what shakeeb said to global gallery and global gallery claims its an error in autoptimize and rapid load.. * I have such a headache from this situation…. If I disable autoptimize and rapidload then the error stops ! but if I activate then the error appears. here is the global gallery creator answer * ``` Those classes are perfectly normal, the point is in the reason why some of them are not elaborated. In other words is what I said on my past reply: for watever reason doe to scripts concatenation, only on mobile, the lightbox algorithms go crazy and do not fire the necessary functions to remove the "lcl_pre_first_el" class and to display the lightbox. The algorithms are exactly the same working on desktop on your site and working in any condition on thousands of other websites since 2017. I already debugged on your end and reported what I found: the Lightbox images preload (leading to lightbox show up) was elaborating strange image indexes not matching the index of the image to show, the lightbox never shows up. I can confirm sometimes concatenating and re-minifying some scripts (JS or CSS) makes them go mad. It's just about excluding a single script ``` - This topic was modified 3 years, 10 months ago by [chendaniel](https://wordpress.org/support/users/chendaniel/). - This topic was modified 3 years, 10 months ago by [chendaniel](https://wordpress.org/support/users/chendaniel/). * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fconflict-plugins-error%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 9 replies - 1 through 9 (of 9 total) * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [3 years, 10 months ago](https://wordpress.org/support/topic/conflict-plugins-error/#post-15871568) * > It’s just about excluding a single script * so have you tried excluding that single Global Gallery script from JS optimization? 🙂 * Thread Starter [chendaniel](https://wordpress.org/support/users/chendaniel/) * (@chendaniel) * [3 years, 10 months ago](https://wordpress.org/support/topic/conflict-plugins-error/#post-15871583) * Yes, but who knows if I did it properly… is there way that I can share my login and details and youll check ?
