Can't access external MySQL login settings while IN_DEV true

[iSeekGolf]

I am using Invision Community v4.3.3 in our testing server.

When I go to System -> Settings -> Login & Registration -> Methods, if I click on "Edit" next to MySQL Database I get "mb_substr() expects parameter 1 to be string, array given" in system/Http/Url.php line 823.

If I turn off developer mode by setting "define( 'IN_DEV', false);", then I can access the externa MySQL settings.

When I installed the IPS Developer Tools, I left in the "applications" folder only the following subfolders: calendar, convert, core, forums; I removed everything else since I couldn't see those in my installed applications folder on the server. I did that because in the Developer Tools documentation it says you should remove apps that you don't have installed from the downloaded dev tools.

However I have a feeling that my developer tools are missing something, I wonder if anyone knows what is it that I should add?

Turn off dev mode, edit the login method... What's in the 'Forgot Password Url' field? 

Try emptying it, saving, then turning dev mode back on.

[iSeekGolf]

That was it mate. I have noticed that that specific field sometimes causes issues, even when not in dev mode.

For example some time ago I tried to edit and entered a complete and valid https URL, then went back to the form later and the field contained only "http://" (and nothing else).

I guess I'll keep the field empty for the time being. Too bad because I would like to take advantage of that feature.

Thank you for your help!

You might consider submitting a bug ticket to IPS if you can consistently replicate.

I've submitted a patch to resolve this issue in an upcoming maintenance release.
