Hello,

Were you updating your system?

Can you access the JEvents backend to view the support information?

Many thanks

Hello,

Are you migrating from a really old installation?

Many thanks
Tony

I had migrated from an older version which went well with no errors. Then along came J6.2, so I updated to it. Then I updated from JEV 3.4.15 (I think) and got the error.

Hello,

Can you delete the indexes from your category #__jevents_catmap table and try again?

Many thanks
Tony
