Error after Update to Joomla 2.5

[neotrend]

Hi

I updated Joomla from 1.7.4 to 2.5.1. Frontend ist working fine, but when I access the files in the backend, the following error shows up, and no items are listed:

Code: Select all

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/xxx/public_html/libraries/joomla/database/database/mysql.php on line 287

I have Phoca Download 2.1.4 installed, no Plugins.

Hope someone can help me.

Perfect found the error. It was

Code: Select all

Unknown column 'a.userid' in 'on clause' SQL=...

so I run the following SQL statement:

Code: Select all

ALTER TABLE `joom_phocadownload` ADD   `userid` int(11) NOT NULL default '0' AFTER `description` ;

and problem was solved. Thanks.
