I've been trying to clear the caches prior to running this EE upgrade but when I do I'm getting this error:

A Database Error Occurred
Error Number: 1054

Unknown column 'rel_data' in 'field list'

UPDATE pfra_relationships SET rel_data = '', reverse_rel_data = ''

Filename: libraries/Functions.php

Line Number: 1205

« Back

I don't think this is going to help my overall upgrade path on this project but would be good to know what's going on.

  • What version of EE? Pre-2.6 I assume? – Derek Hogue Dec 16 '13 at 13:10
  • yeah, it's currently running 2.5.5 – Steven Grant Dec 16 '13 at 13:33
  • And if you look at the prfa_relationships database table, what columns does it have? – Derek Hogue Dec 16 '13 at 14:27
  • turns out this was related to my botched upgrade process - answer to follow – Steven Grant Dec 16 '13 at 19:23

So the config file for this site had:

$db['expressionengine']['swap_pre'] = "pfra_";

when it should in fact have been

$db['expressionengine']['swap_pre'] = "exp_";

even although the db tables are all set with a prefix of pfra_
