Maybe it's because you have older php versions running that you can't build the 1.6.0. You have to keep with 1.5.3.RoundCube 1.6.0 cannot run on php 7.3 or older
yes brotheryou from thailand ?
I suggest to rebuild mysql after set "mysql_force_compile=no" if still not work, trying remove/rename da_roundcube database to force rebuild all thing about roundcube
I also have the same during backup, how to fix it?You might best send in a ticket, seems there probably is an issue/bug.
Seen the same here:
