Yes, as Bernard said, you can fix this in phpmyadmin or similar, you just need to clear the "waiting" field on the admin row in the users_users table.
Or you can use this handy bash script a colleague of ours added:
I'm still a bit confused on how to log in (the waiting field has an (A) which I removed but then when I tried to log in it, said over 50 attempts had been made.
Where do I add this? Or you can use this handy bash script a colleague of ours added:
Would it be easier if I remove the lock and then install tiki-21.4 will this sort out the issue? I am currently on ver 21.2
Thanks again for the help.
