Related Items Error

Hi, good afternoon.
Updated to 2.7 Beta 3 (inc. extension). I'm getting the following error on my sub-entities on the Item Listing page:

Database Error: 1558 - Column count of mysql.proc is wrong. Expected 21, found 20. Created with MariaDB 100108, now running 100411. Please use mysql_upgrade to fix this error
Query: select e.* ,rukovoditel_days_diff(e.field_265,e.field_255,'','1','') as field_1409 from app_entity_30 e where e.id>0 and e.parent_item_id='251' order by e.date_added asc limit 0, 10
Page: /rukovoditel_2.7/index.php?module=items/listing

I've run the php update script as part of the install, so I'm wondering if it's a Ruko error, or a problem with my server.
Any suggestions?
Thanks in advance
Stuart

Looks like issue with your server. See https://stackoverflow.com/questions/161 ... is-probabl
Try restart mysql.
