Installationsproblem with 2.5.6

[wolwes]

Hallo,
I have installed 2.5.6 (Update),before 2.2???. In the Tab Picture in the Backend there is a Problem:

mysql_num_rows(): supplied argument is not a valid MySQL result resource in /share/HDA_DATA/Qweb/Joomla/libraries/joomla/database/database/mysql.php on line 344

In MySQL there are six tables. In the first are my pictures. In the Frontend also are my pictures.

greetings
Wolfgang

I have solved the problem.

there was during the installation a error:

Allowed memory size of 8388608 bytes exhausted (tried to allocate 98304 bytes)....

There was in my qnap-nas-server memory_limit=8M, too little. I have changed it to 20M. Now is it o.k.

Tolle Komponente!

Wolfgang
