I installed several plugins from GaMerZ. I believe one of them made it so the CSS in other plugins doesn't work, specifically share-this 1.4, Spotmilk and sem-admin-menu. (Admittedly, I may have tried to activate one of the GaMerZ plugs before the Plugins page refreshed.)
I deleted the GaMerZ plugs and still the others' CSS doesn't work.
Anyone else seen something similar? If so, what's the fix? Is there one? Re-install WP?
Thanks in advance.
