Topic: Upgrade from V475 to V521 SQL errors
I'm trying to upgrade from V475 to V521 but have struck an error. According to the error log, it comes up with the following errors ..
ERROR Script: /luxcal/display1p.php - SQL query error: SQLSTATE[42S22]:
Column not found: 1054 Unknown column 'c.olapGap' in 'field list'
... and seems to be related to the displayx.php files. The above error message is the first of many in the log file.
The PHP version running on the server is V5.5.34
Has the structure of the database tables changed i.e. more columns ?
If so, do I need to prep the tables with these new columns ?
I do make copies of database tables via phpMyAdmin in csv format. So I haven't lost any data and have re-instated the older version (V475) for now.
But the PHP Session Timeout issue is a BIG PROBLEM for us so am keen to upgrade asap.
I have noticed that the upgrade script has prepared the database tables (mycal_....etc ) by creating a copy of all tables and appending X at the end.
I can send the SQL error log file if required.
