i have installed nextcloud through the plesk extension and everything works fine.
Onlyoffice and the Community Document Server are working and uptodate.
I’m trying to use mail merge between a spreadsheet and a textdocument, but always get an errormessage when i try to import the xlsx file: Fehler beim Laden (error at loading).
I have created a spreadsheet in the same folder, according to this helppage: https://helpcenter.onlyoffice.com/ONLYOFFICE-Editors/ONLYOFFICE-Document-Editor/UsageInstructions/UseMailMerge.aspx
Has anyone else had this error and knows a fix? The error is so unspecific, i have no idea what could be the cause.
Thanks in advance
