no access to plugin page in backend

hi,

i just updated a plugin and afterwards the error occured.

all plugins are still installed, but i don’t have any access to them via the plugin-page in the backend (critical error).

i’m not sure if this is only caused due to the update or if there is another problem.

i would be very thankful for any hint. thanks in advance!

anne
