Error messages on images tab

[cmsdev]

I just installed phoca on joomla 2.5.3 and am getting these messages:

Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given in /homepages/16/xxx/htdocs/domain.tv/libraries/joomla/database/database/mysqli.php on line 263


Warning: Invalid argument supplied for foreach() in /homepages/16/xxx/htdocs/domain.tv/administrator/components/com_phocagallery/libraries/phocagallery/render/renderadmin.php on line 70

Also, when trying to create a category, I get:

Save failed with the following error: Category must have title

...even though I have added a title. What's wrong?

Thanks, but I'm not a programmer, so the info it is spitting out doesn't help me much. Can I PM you a super admin login so you can take a look at it?

[Jan]

Hi, admin login does not solve anything until error messages are not displayed

[cmsdev]

I don't think you understand me; I did enable error message display, but don't understand how to fix.

Would you mind if I PM you a super admin login so you can take a look at it?

Hi, I see php error message here in this forum, but to get the main info, you need to enable debug mode, which says which error you get in database - you will get message (mostly e.g. that some table is missing) ... this is not related to php programming.
