Title: Mobile Cache Issue Research Last modified: January 3, 2025 --- # Mobile Cache Issue Research * Resolved [gnetconsulting](https://wordpress.org/support/users/gnetconsulting/) * (@gnetconsulting) * [1 year, 5 months ago](https://wordpress.org/support/topic/mobile-cache-issue-research/) * Every few days the events page breaks the layout when on mobile when desktop looks fine. See this image: * [https://crawlstreet.com/wp-content/uploads/2025/01/Crawl-Street-Cache-Issue.png](https://crawlstreet.com/wp-content/uploads/2025/01/Crawl-Street-Cache-Issue.png) * The site uses the SiteGround Speed Optimizer plugin, and have set the following URL’s not to cache: * /events/ /wp-content/plugins/the-events-calendar/(.*).css/wp-content/plugins/ the-events-calendar/(.*).js/wp-content/plugins/event-tickets/(.*).css/wp-content/ plugins/event-tickets/(.*).js * Is there anything else we can check? I believe it’s cache related b/c when I clear the cache and refresh on mobile, it loads fine. I did test the /events/ URL and the SG plugin says it’s not cached. We are also not combining any CSS or Javascript. * TIA! * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fmobile-cache-issue-research%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 15 replies - 1 through 15 (of 15 total) * Plugin Support [tristan083](https://wordpress.org/support/users/tristan083/) * (@tristan083) * [1 year, 5 months ago](https://wordpress.org/support/topic/mobile-cache-issue-research/#post-18224873) * Hi [@gnetconsulting](https://wordpress.org/support/users/gnetconsulting/) , * Thank you for reaching out. * For us to understand and learn more about your setup, could you provide the version of the following? 1.

I will not clear the cache so you can see it. I see it on my Samsung phone. * I will turn on debugging now, as well. * Thread Starter [gnetconsulting](https://wordpress.org/support/users/gnetconsulting/) * (@gnetconsulting) * [1 year, 5 months ago](https://wordpress.org/support/topic/mobile-cache-issue-research/#post-18229933) * I installed the plugin and I reloaded the events page. It’s now loading as normal.

It may be related to when automated WordPress updates are made. I will try and confirm that. * Outside of that, these are the messages I see, if it helps at all. It doesn’t look like it has anything to do with this issue, but will pass along. `[09-Jan- 2025 12:55:29 UTC] PHP Warning: Undefined property: WP_Post_Type::$term_id in/ path/to/public_html/wp-includes/taxonomy.php on line 1709``[09-Jan-2025 08:58: 12 UTC] PHP Deprecated: rtrim(): Passing null to parameter #1 ($string) of type string is deprecated in /path/to/public_html/wp-includes/formatting.php on line 2819` * Plugin Support [tristan083](https://wordpress.org/support/users/tristan083/) * (@tristan083) * [1 year, 5 months ago](https://wordpress.org/support/topic/mobile-cache-issue-research/#post-18238884) * Hi [@gnetconsulting](https://wordpress.org/support/users/gnetconsulting/) , * Thank you for your message and the information. * Looks like those are warning and deprecation notifications that don’t really stop program execution. As such, we may be dealing with a conflict here and not just caching. It would be good to test for conflicts. Could you follow the following steps? 1. Deactivate all other plugins except for The Events Calendar Plugins. 2. Switching to the[ Default theme](https://codex.wordpress.org/WordPress_Default_Themes). * Please read the [Testing for Conflicts Article](https://theeventscalendar.com/knowledgebase/k/testing-for-conflicts/) before doing anything.  To be safe, we’d recommend conducting tests and updates on a [Staging Server](https://theeventscalendar.com/knowledgebase/k/creating-and-using-a-wordpress-staging-site/).
