I have been using egroupware community version for a while and it was fine before.
But from this week, it kept on popping up an error message which says:
Invalid SQL: SELECT * FROM egw_etemplate WHERE et_name='.notifications' AND et_template='' AND et_lang='##' ORDER BY et_lang DESC,et_template DESC,et_version DESC:
MySQL server has gone away
I want to fix this because it's very annoying.
I think it's caused by something that I set wrongly.
I didn't customize the software
