Checked permissions on the plugins folder, it is correct (755, 644 on files). I changed themes, I re-installed the wordpress files, no difference. These are the same plugins and theme that was working on my previous webhost -- only the database was changed (imported from a backup from another webhost). So, I don't know if something in the SQL database can affect the settings option on "most" plugins in the admin panel? Otherwise, I'm fresh out of ideas. Anyone that might be able to give me a clue?
[No bumping, thank you.]
