Reply To: Split: issue with theme custom css! :(

Hello,

Please restore the site from the backup, deactivate all the plugins, update the theme, update the plugins in Appearance > Install plugins.

Then activate the plugins in Appearance > Install plugins and then activate other plugins one by one to detect which one causes the problem. We recommend updating other plugins as well before activating.

Please let us know if the problem presists.

Best Regards
