After converting from phpBB none of my users can log in

[Mick23]

Hi folks,

I upgraded my old phpBB (3.3.2) site to Invision and everything went brilliantly until the users attempted to log in.

Even my own test accounts that had been converted gave me a wrong password error and locked me out after 3 attempts.

Has anyone experienced this problem before and know how to fix it?

My members will not be happy if they all have to reset their passwords after the switch, and I really don't want to have to manually delete everything and re-convert.

Please help!

After much digging around it turns out the the passwords on the phpBB forum have been set using the argon2 hashing algorithm (due to a change in php versions).

When the conversion runs, these passwords are not imported correctly into the member_pass_hash and members_pass_salt fields in the core_members table which causes the logins to fail.

I'm not sure there is a solution for this except for everyone to change their passwords when they log into to the upgraded site.

Any assistance would be greatly appreciated. I'd hate to have wasted my money on it 🙂
