Is it normal to get notifies in debug mode?

[dEnA]

As I asked in subject, i changed server and had different problems which I solved thanks to this forum, but I couldn't find this and can't remember from before..

On front page I get this error for example:
Notices
/bridge/udb_base.inc.php
Notice line 149: Undefined property: multigroups

viewing a image:
Notices
/bridge/udb_base.inc.php
Notice line 149: Undefined property: multigroups
/include/themes.inc.php
Notice line 2202: Undefined index: uid
Notice line 2286: Undefined variable: report_tgt
Notice line 1905: Undefined index: uid
/displayimage.php
Notice line 351: Undefined variable: meta_keywords

And so on.. Everything seems to be working, just worried

Ps. I had to change my image mode from imagemagick to GD 2 and I allready have houndreds of photos, does it matter and/or do I have to do something more?

Thanks

Don't worry those are harmless (just ignore them and turn them off)

and No it does not matter and you shouldn't change anything else ...

You shouldn't have enabled display_notices in the first place.
