Hello fellow mw users, I just had to reinstall my server, and I did a backup of mw afterwards. My setup: VPS running CentOS6 64x, custom installer script for mw and powermta. After running the installer I uploaded the entire mw folder per ftp In phpmyadmin deleted all tables in mailwizz database and imported my backup.sql The file was too big, so I had to split it. Although theoretically I could upload files up to 64MB big, the upload timed out on my 13MB zip file. I used SQL Dump Splitter, and imported the files. All went smooth, phpmyadmin reported all imports as successful. I opened mw and on first sight, all looks good. My lists are there, my campaigns are there. But whenever I try to open the info on a campaing, or try to go to page two of my campaigns, or try to set the number of campaigns shown I get this error: " Error 500: CDbCommand failed to execute the SQL statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'operator.' in 'where clause' " Looks like mw is looking for a column that's not there? Can I find out what column that is and where it should be? I can see all my 79 campaigns in the mw_campaign table. Could the Dump Splitter have caused the problem? I guess I could try to import the database via bash line, although I am not sure where to find my database user and password I'd appreciate any help - Thxs !
