Hello There,

Thanks for writing in! This error comes from the W3 Total Cache plugin. Please deactivate this W3 Total Cache and save your page changes. If you need this plugin, please find out first if your server has the minimum requirements to run WordPress and to run this plugin. You can check it out from here: https://wordpress.org/about/requirements/

Hope this helps.

Hi There,
Its a shame that after lot of work and try outs with W3 Total Chache my webite is loading quite fast, but I am currently experiencing a lot of problems (I think because of W3 Total Chache). All interactive functions failed working (like counter and flipping iccons). Can I uninstall W3 Total Chache without problems and then reinstall it and make a fresh start? Or will this leave a lot off code behind that causes problems?

My Server has more then the minimum requirements to run WordPress and to run W3 Total Chache that is not the problem.

Caching plugins might leave settings that might cause issues. Please see this article to completely uninstall W3 Total Cache. Caching plugin in general are useful. But, it needs to be configured by a professional in order for it to work specifically for your setup.

Thanks.

Hi There,

Thank you for your advice I did completely uninstall W3 Total Cache and did reinstall a clean version and fatal error message is gone.

But I’m afraid some permanent damage has been done, two Clasic Card elements have become tangled up together and I can no longer approach/select them in Cornerstone, they have become a kind of ghost elements, the strange thing is that they are oke on the mobile smart Phone still in the right place and functioning. Also on my homepage interactive elements have stopped functioning such as the counter and the flip cards. Google map in my contact page is also gone on desktop but still there on mobile??

Please clear all caches and completely uninstall W3 Total Cache while we investigate because we need to know if the issue is in X and not third party factors. I tried to clear cache but this is what I get.

Thank you for your cooperation.

flowdivision · January 16, 2018, 1:56pm

Hi there, I just cleared all caches and completely uninstalled W3 Total Cache
Thank you for your support!

Sorry I just discovered one possible cause also. You’re using Cloudflare and Rocket Loader. Please disconnect your site from Cloudflare also for troubleshooting.

Thanks.

flowdivision · January 16, 2018, 4:40pm

Current Status Cloudflare: Paused
Plugin Cloudflare: Deactivated

are the above mentioned actions sufficient?

friech · January 16, 2018, 9:04pm

Hi There,

Please follow the solution provided here, ie. adding a page rule to exclude Cornerstone from being cache and deactivating the Auto Minify JavaScript and CSS feature. Also on the Speed panel please deactivate the Rocket Loader.

Lastly, under the Caching panel, please Purge Everything so the cache will be regenerated with the new settings.

Let us know how it goes,
Cheers!

Hi there,
I am very pleased with your advice and support, all broken parts of the X theme are fixed, thank you

I folowed your instructions and altered Cloudflare, I would like to reinstall W3 total cache can I minify JavaScript and CSS in W3 total without any problems? Are there any instructions or information for aplying the right settings so W3 total will not break my site again?

I like to start using maxcdn on my site, are there any problems to be expected like with cloudflare?
