Title: Plugin updates break site layout Last modified: March 30, 2026 --- # Plugin updates break site layout * Resolved [dleigh](https://wordpress.org/support/users/dleigh/) * (@dleigh) * [2 months, 1 week ago](https://wordpress.org/support/topic/plugin-updates-break-site-layout/) * Hi, * LiteSpeed report: **LIVYHQGT** * On our site, when a plugin or the theme is updated automatically (via Easy Update Manager) the layout of the site breaks. If I log into the admin of the site, that simple act fixes it (i.e. I then log back out and go to the home page and the layout is fixed). This has happened with the theme or with many different plugins. I’ve set up a staging site cloned from our production site. I’ve disabled all plugins except for LiteSpeed, Easy Update Manager and I picked a random plugin, MailPoet, for testing. I upload an older version of MailPoet and then wait for Easy Update Manager to do its thing and update MailPoet. It does so and the site breaks. * Looking at your “Read this before posting” post, I disabled LiteSpeed and the update does NOT break the layout. Then I reenabled LiteSpeed and just turned off the Cache and the update DOES break the layout. The conclusion in your “Read this before posting” is that it’s an optimization issue. * Does the LiteSpeed report I sent indicate what I might need to change in the optimization? * Thanks! * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugin-updates-break-site-layout%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) * [2 months, 1 week ago](https://wordpress.org/support/topic/plugin-updates-break-site-layout/#post-18868278) * [@dleigh](https://wordpress.org/support/users/dleigh/) Thank you for report number. Let’s test a change. Please disable Object Cache([https://docs.litespeedtech.com/lscache/lscwp/cache/#object-cache](https://docs.litespeedtech.com/lscache/lscwp/cache/#object-cache)) and test updating the plugins.Thank you * Thread Starter [dleigh](https://wordpress.org/support/users/dleigh/) * (@dleigh) * [1 month, 2 weeks ago](https://wordpress.org/support/topic/plugin-updates-break-site-layout/#post-18888657) * Thanks for your patience! It’s been an up and down few weeks. * I just tested with “enable cache” ON and “object cache” OFF and the problem still exists. * I’m still using the same method to test as outlined in the OP. * Plugin Support [litetim](https://wordpress.org/support/users/litetim/) * (@litetim) * [1 month, 2 weeks ago](https://wordpress.org/support/topic/plugin-updates-break-site-layout/#post-18888825) * [@dleigh](https://wordpress.org/support/users/dleigh/) I tested the site now and I see the site broken. Also tested the site with this parameter [https://staging.gsgsrescue.org/?LSCWP_CTRL=before_optm](https://staging.gsgsrescue.org/?LSCWP_CTRL=before_optm) which disable all LSC optimization changes(minification, combine…) AND the staging site is not cached. This basically disables LSC.Maybe something else is not refreshing the cache. * Thread Starter [dleigh](https://wordpress.org/support/users/dleigh/) * (@dleigh) * [1 month, 2 weeks ago](https://wordpress.org/support/topic/plugin-updates-break-site-layout/#post-18888841) * Thank you for testing that. Could you perhaps give an example of what else might be affecting a cache in this circumstance? Would this be a cache that LiteSpeed doesn’t manage? * For my understanding of caching, it seems that there are several “layers” of caching that are involved with a WordPress site. I may not be correctly understanding that. * I do note, again, as I did in my OP, that when I disable LSC, this plugin update process proceeds without breaking the site. If the problem isn’t with LSC, it’s at least something that interacts with LSC when it’s enabled. * Thread Starter [dleigh](https://wordpress.org/support/users/dleigh/) * (@dleigh) * [1 month, 2 weeks ago](https://wordpress.org/support/topic/plugin-updates-break-site-layout/#post-18888852) * Another thing that might help. When access the site: - after an update AND - after cache has been refreshed via the admin interface AND - on another browser or in incognito mode * I will see a Flash of Unstyled Content (which looks like the broken version of the header) on several of the pages THE FIRST TIME I access them. After that, I don’t see the FOUC – even if I re-open the page in a brand new browser or a brand new incognito session. * So, it’s as if, once the cache has been “fixed”, there’s still a “broken” version that is flashed and then replaced. * Thread Starter [dleigh](https://wordpress.org/support/users/dleigh/) * (@dleigh) * [1 month, 2 weeks ago](https://wordpress.org/support/topic/plugin-updates-break-site-layout/#post-18888853) * Right now the site is “un-broken” again. I’m going to upload the old MailPoet version now so as to re-invoke the sequence that breaks the layout the next time that automatic updates happen. So if you’d like me to change a setting on LSC, please let me know. * Plugin Support [litetim](https://wordpress.org/support/users/litetim/) * (@litetim) * [1 month, 2 weeks ago](https://wordpress.org/support/topic/plugin-updates-break-site-layout/#post-18889171) * [@dleigh](https://wordpress.org/support/users/dleigh/) OK Try this: disable LSCWP plugin. And let the update run.Do you get the same result? - This reply was modified 1 month, 2 weeks ago by [litetim](https://wordpress.org/support/users/litetim/).
