something must have gone wrong with a recent update (Joomla and Yootheme). But when trying to restore a backup before, only an error message comes up (see screenshot).
What is the cause How can I eliminate the error? Can you help me with this please?
Error after delete htaccess:
Extraction of the backup archive has failed.
The last error message was:
Could not open /home/abonaerp/public_html/ABONA2020/test.txt for writing.
