What I've done so far:

1. Reinstalled wordpress

2. Disabled all plugins except Pencil ones

3. Reinstalled Soledad

Problems are still there :/

Would you please help me on that?

Hi,

So I completely deleted CloudFlare and waited for the replication to take place correctly. 
I will see later to install another CDN.

Could you please repeat the tests and see if the problems are still there or not.

Thanks for your help.

Best regards,

Nicolas

Hi,

Thank you for the video with the detail of the problem. I am trying to see with my host but the problem would come from a problem between Cloudflare that I use and their firewall. Their recommendation is to stop using Cloudflare, do you know an alternative to Cloudflare to speed up and protect my site? I made some changes to the Cloudflare rules, could you retest to see if there are still the same issues with javascript files from the theme?

Thanks for your help !

Best regards,

Nicolas

Hey,

I got feedback from my host's technical support. According to them the problem can come from the ModSecurity module in the Cpanel. So I disabled ModSecurity.

Are you still having the same problems?

Is it dangerous to leave ModSecurity disabled?

Thanks for your help!

Hey,

I opened a ticket with my provider explaining the problem to them.

I await their response and I will keep you posted!
If you have any other technical remarks about my provider and the problème, don't hesitate to tell me I will transfer the necessary technical requests to them.

Thank you !

Hi, 

I disabled all plugins and the PHP memory is increased to 512M. Unfortunately the problem is still there. Do you have any other idea what I could do?

Best regards

Hi,

When I want to customize the display of the template, I have an empty window. I have tried different browser but the problem is the same. Do you have any idea how to deal with the problem please. Thank you !
