No, my hosting company didn´t fix the issue. It burdens servers and mistakes happens all the time, so that´s why it is off.
@rogierlankhorst Thank you for your help. Version 6.14 works fine. Error log still off.
Thank you Rogier, error log is off, probably due to the lightening of the web hosting server. WP_debug hasnť resolved the issue.
Until version 6.1.2 it worked fine. Is it possible to fix this issue?
