Here I am again with an error of my gallery ;)

I see where the problem is, but I´m not exactly sure what I can do about it, how it happened for I didn´t change anything (yeah, I know EVERYONE says that) and I also didn´t want to make it worse. Any help is hugely appreciated. Thanks.

That doesn´t seem to possible. If I try that, I get another output, though.

Before the debug output the following is displayed: (But that doesn´t seem to be connected to the forementioned error... or is it?)

I suppose I have to do do something in the database itself?

Thank you for your answer.
I executed the following sql:
UPDATE g2_PluginMap SET g_active=0 WHERE g_pluginId='customfield';# Betroffene Datensätze: 1

DELETE FROM g2_FactoryMap WHERE g_implModuleId='customfield';# Betroffene Datensätze: 3

Then I tried to empty the cache as explained here: http://codex.gallery2.org/Gallery2:FAQ#How_can_I_clear_cached_data.3F
After I had typed in my password I get the following. Now, I can´t make anything out of that.

Wow, thanks a lot! The gallery is up again. Everything worked the way you suggested!
THANK YOU!
