XF 1.5 Duplicate entry for key 'expiry_date'


servers shutted down and now I've this error. Is it fine to just "repair" the XF_session table?
Note: in phpmyadmin, XF_session table is marked as "under use" (literally translated from my language)

Mysqli prepare error: Table './forum_xf/xf_session' is marked as crashed and should be repaired

Thank You @Brogan & @daimpa

I just had exact same error message, and REPAIR xf_session table through phpMyAdmin worked perfectly.

Do you guys have any idea how can I see all corrupted table list in my database (phpMyAdmin) ?
