I installed the flattr-plugin and went to the settings to configure it.
After I did enter the API-keys and saved the flattr-settings screen went empty and also in the backend all options are no longer expanded. I tried to reload the flattr settings but still it's empty.
I thought it could be a memory problem but even setting the mem to 128 MB in the config did not help.
I guess this might have something to do with the fact I'm using custom post types...
Any insights please?
