After Wordpress Update, a warning is shown on the sites with pro child Theme

Dear Support,

After Updating to Wordpress 5.3.2, i get a warning on the pages with the message:

Warning: ftp_fget() expects parameter 1 to be resource, null given in /home/.sites/93/site37/web/wp-admin/includes/class-wp-filesystem-ftpext.php on line 143

Because i can not find the source for this warning, and also not make it disappear by disabling all installed plugins,
I thought may be you can help me, if its related to the theme (pro - child theme).

Thank you!
All the best

Hi Robert,

Thank you for writing in, more likely it is a plugin conflict. Please do a testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.

If the issue persists, please provide us login credentials in a secure note so we can take a closer look.
