Hey Toni,

Please delete the enfold folder and upload a fresh copy of the theme and see if the issue gets resolved.

Hi Gamefrequenz,

Before you do anything, can you tell us what PHP version you’re using? can you try to switch to PHP 7.3?

Best regards,
Nikko

Hi Nikko,

Im using PHP version 7.4. I can go back to 7.3. But why? And before I upload a fresh copy of enfold?

Hi,

Thanks for the update. Could you provide us WordPress login details as well please? I checked the FTP space as well, but I’m not sure exactly where the site in question is located?

Best regards,
Rikard

Hi Gamefrequenz,

Thanks for the FTP access, you should be able to login now.
And I apologize for the misunderstanding, I thought you were already using the latest version.
Please update from version 4.5.5 to 4.7.6.3. :)

Best regards,
Nikko

Hi Toni,

You’re welcome. :)
There’s a minor bug in the code that only shows to some people (most likely due to server settings) and this was fixed in the later versions of Enfold.

Best regards,
Nikko
