Following updates to my devel installs, I had problems with both installs on 1 server, as follows.
I could not log in or out.
I was getting warnings and notices, as follows;
Notice: Array to string conversion in /web/sites/14/langportrd/www.langportrd.f2s.com/galleries/include/debugger.inc.php on line 47
Warning: Cannot add header information - headers already sent by (output started at /web/sites/14/langportrd/www.langportrd.f2s.com/galleries/include/debugger.inc.php:47) in /web/sites/14/langportrd/www.langportrd.f2s.com/galleries/themes/water_drop/theme.php on line 848

There were also other notices. Changing themes did not help.
On investigating the debugger.inc.php file, the first thing I noticed is there is no closing '?>' at the end of the file.
I applied this, but it did not help.
I then commented out line 47, shown here;
$this->old_handler = set_error_handler(array(&$this, 'handler'));
Commenting this out solved most of the problems, but notices are still displayed at all times, such as these;
Notice: Undefined index: cat_thumb in /web/sites/14/langportrd/www.langportrd.f2s.com/galleries/themes/water_drop/theme.php on line 1083
Note, this did not affect my devel install on my other webhost.
My php info is attached.
