I've found that modifying the line 169 to change it from a reference to a literal assignment works.

$AdminUI = & new AdminUI();

to

$AdminUI = new AdminUI();

Not the best solution, but it seems to eliminate the problem, which came with the upgrade to 5.3.x which is the party that [url=http://php.net/manual/en/migration53.deprecated.php]deprecated assigning new as a reference [/url]. I suppose this may cause an increase in required memory, but I haven't notice any negligible consequences from the change.

Note: those notices appear in PHP 5.3 only.

b2evolution 3.3.3 automatically disables those notifications if your PHP config allows it. If not, you can manually disable these notices in php.ini.

b2evolution 4 removes all the = & new and replaces them with = new.

Hi.

I made a patch for this:

http://lukas-schauer.de/depr_new.patch

or if you have "exec-rights" on the server you can use this php script in the root of your b2evolution installation:

http://lukas-schauer.de/fix.php.txt

the php-script should work with every php-application using "& new" in php-files but i wrote it just for b2evolution so no warranty on this :-P

Edit:

there could be this message:

patching file skins/BlogIt/_feedback.php
Hunk #1 FAILED at 91.
1 out of 1 hunk FAILED -- saving rejects to file skins/BlogIt/_feedback.php.rej

don't worry it's just because i had installed the BlogIt-skin while creating the patch

If you can edit your php.ini file (and you are able to find it), modify the error_reporting directive:

error_reporting  =  E_ALL & ~E_NOTICE & ~E_DEPRECATED

On most standard installations of php, you'll just need to add the "& ~E_DEPRECATED" to the end of the directive value. This is the manual way to change the level of error reporting without core hacking.
