The current version of my glossary extension works fine when already installed and updated, but not when installed from scratch. The error message is:
A migration is invalid. An unknown migration tool type was encountered.
Before that, I get following warnings:
[phpBB Debug] PHP Notice: in file [ROOT]/phpbb/db/migrator.php on line 728: Undefined offset: 0
[phpBB Debug] PHP Notice: in file [ROOT]/phpbb/db/migrator.php on line 729: Undefined offset: 1
This is in function
get_callable_from_step
, called by run_step
.Do you happen to know where I should search?
Thanks in advance.
