sorry for asking this novice question:
yesterday i added some templates and everything seem fine.
Today, each time i try to install the template zip files (which are basic templates ,unmodified, and downloaded directly from the templates list in WB website ) i got a "cannot upload file", no matter each template.zip i try to install .
Sorry if there's .. i don't know what indeed i do wrong & which i was doing right yesterday, it's simply a day of work ruined cause i can't go any further & i'm totally clueless
ty for your help, i guess there must be a simple answer
