 * Hello [@andronidko](https://wordpress.org/support/users/andronidko/)
 * I hope you’re well today!
 * Thank you for reporting this and suggesting solution.
 * However, I did try to replicate this on my test site but to no success. I’m believe
   there must be some additional reason to this than only Custom Sidebars being 
   active. Could you tell me please
 * – did you test it with only Custom Sidebars active and no other plugins at the
   same time?
    – what theme are you using and did you also try with just Twenty 
   Nineteen or Twenty Twenty? – where are you hosting (and possibly what kind of
   plan – if there’s a choice of e.g. shared/VPS/Managed plans at your host)? This
   question is only to help me find differences between my test environment and 
   yours and possibly (if I’ll have a chance) test the issue on the same or similar
   host
 * Best regards,
    Adam

 * Please i need help on this.
 * Unable to communicate back with site to check for fatal errors, so the PHP change
   was reverted. You will need to upload your PHP file change by some other means,
   such as by using SFTP.
