SYMPTOMS
After the Plesk upgrade, subdomain creation page in Plesk ( Plesk, Domains, domain.tld, subdomains, Create New Subdomain ) displays the number of warnings:ERROR: unmatched tags still present in feature_edit
ERROR: unmatched tags still present in subdomain
ERROR: unmatched tags still present in form
ERROR: unmatched tags still present in main
CAUSE
The reason of the problem is that some files were not upgraded because they had been replaced before – it could be some hotfixes provided with support and installed manually.RESOLUTION
Please download the following filehttp://download1.swsoft.com/Plesk/Autoupdate/Windows/8.2.0/126047/class.SubDomainManager.php
and place it to %plesk_dir%\admin\plib\
Note: Please see how to install Plesk hotfixes properly.
