Errors with Somme Versions of PHP

[jmgroud]

Hello

I'm using Joomla 2.5.7, and Akeeba to backup my WebSite.
With Akeeba, I can't stay with an old version of Php...
My version is 5.4.7.
Now I have somme error with Phoca Download version 2.1.6

For exemple when i try to create a new catagorie :
Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in /homepages/...../libraries/joomla/database/database/mysql.php on line 293
It's a warning... but if i try to continue :
Warning: Invalid argument supplied for foreach() in /homepages/...../libraries/joomla/database/database/mysql.php on line 383
Warning: Invalid argument supplied for foreach() in /homepages/...../administrator/components/com_phocadownload/helpers/phocadownload.php on line 19
It's a warning... but if i try to continue :
L'enregistrement a échoué avec l'erreur suivante : CATEGORY MUST HAVE A TITLE

I can't use Phoca Download
(my WebSite is by "1&1")
Thanks a lot for a solution if possible.

Hi, enable debug mode which says you which error you get in database.
