Title: Conflicts in page optimization settings Last modified: July 7, 2026 --- # Conflicts in page optimization settings * [helenatan0169](https://wordpress.org/support/users/helenatan0169/) * (@helenatan0169) * [3 days, 22 hours ago](https://wordpress.org/support/topic/conflicts-in-page-optimization-settings/) * Hi Team After testing, I found that whenever I enable the “Generate UCSS” option within the CSS settings (under Page Optimization), the navigation bar and product filter bar fail to open on mobile and tablet devices.I am using the Iks Menu plugin. When the optimization is disabled, the sub-category products on the page [https://championleathercase.com/products/](https://championleathercase.com/products/) work correctly—clicking them reveals the dropdown menu. However, on product category pages like [https://championleathercase.com/product-category/phone-cases/](https://championleathercase.com/product-category/phone-cases/), clicking does not trigger the dropdown; the dropdown options only appear if I click on the parent category page itself.As soon as I disable LiteSpeed ​​Cache, all the problems simply disappear.This is very frustrating, and I hope to find a solution or a suitable workaround.Last Report Number: **ZKLBUSSL** * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fconflicts-in-page-optimization-settings%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Support [litetim](https://wordpress.org/support/users/litetim/) * (@litetim) * [3 days, 14 hours ago](https://wordpress.org/support/topic/conflicts-in-page-optimization-settings/#post-18958802) * [@helenatan0169](https://wordpress.org/support/users/helenatan0169/) I have tested the IKS menu(free version) I enabled UCSS and some settings that were important.

It require some testing, but it will work. * Thread Starter [helenatan0169](https://wordpress.org/support/users/helenatan0169/) * (@helenatan0169) * [3 days, 7 hours ago](https://wordpress.org/support/topic/conflicts-in-page-optimization-settings/#post-18958987) * Hi Team, * Thank you very much. I managed to fix the issue with the navigation bar not responding when clicked by following your instructions. However, I’ve run into a problem: the dropdown menu works fine when LiteSpeed ​​is disabled, but once I enable it—even after trying various settings—it stops responding to clicks on the page [https://championleathercase.com/product-category/phone-cases/](https://championleathercase.com/product-category/phone-cases/)( specifically on mobile and tablet views). I’m not sure where the issue lies.

Try adding: **html.panel-opened** OR **html.panel-opened #side-nav-panel** to UCSS allowlist * Thread Starter [helenatan0169](https://wordpress.org/support/users/helenatan0169/) * (@helenatan0169) * [2 days, 2 hours ago](https://wordpress.org/support/topic/conflicts-in-page-optimization-settings/#post-18960362) * Thanks for the reply. When I added the first snippet (`html.panel-opened`) you provided, the top menu bar became unresponsive. Adding the second one (`html. panel-opened #side-nav-panel`) resulted in no visible change. I also tried adding both, but the same issue persisted. I have re-sent the reference link for the images. * [https://championleathercase.com/wp-content/uploads/2026/07/b595d7f9445a00237d6ee7c34e00b595.png](https://championleathercase.com/wp-content/uploads/2026/07/b595d7f9445a00237d6ee7c34e00b595.png) [https://championleathercase.com/wp-content/uploads/2026/07/8a4dc28952de43b2fb378b2315fa4680.png](https://championleathercase.com/wp-content/uploads/2026/07/8a4dc28952de43b2fb378b2315fa4680.png) [https://championleathercase.com/wp-content/uploads/2026/07/c4651156-44c2-4700-a941-dec5b8cf54dd.png](https://championleathercase.com/wp-content/uploads/2026/07/c4651156-44c2-4700-a941-dec5b8cf54dd.png) * Plugin Support [litetim](https://wordpress.org/support/users/litetim/) * (@litetim) * [1 day, 19 hours ago](https://wordpress.org/support/topic/conflicts-in-page-optimization-settings/#post-18960822) * [@helenatan0169](https://wordpress.org/support/users/helenatan0169/) Please send a new report. no need to share the ID, just send a new one to Litespeed * Thread Starter [helenatan0169](https://wordpress.org/support/users/helenatan0169/) * (@helenatan0169) * [1 day, 9 hours ago](https://wordpress.org/support/topic/conflicts-in-page-optimization-settings/#post-18961165) * Thank you for your reply.
