[TYPO3-english] Problems with TYPO3 4.x after PHP upgrade

[Pero Peric]

Hi,

Recently we upgraded Debian OS to Wheezy which brings PHP 5.4.x so i got 
many "Strict Standards: Non-static method errors" with some older 4.x 
TYPO3 version. I upgraded this version to TYPO3 4.7.15 but i still have 
problems with this kind of errors on following extensions:

tx_dam
tx_staticinfotables

and also in tslib

Strict Standards: Non-static method tslib_cObj::calc() should not be 
called statically, assuming $this from incompatible context in 
typo3_src-4.7.15/typo3/sysext/cms/tslib/class.tslib_menu.php on line 760

tx_dam and tx_staticinfotables are last versions so i'm not sure what to 
do? Btw. other TYPO3 4.7.15 installation i have is running ok (without 
this kind of errors) so it's a bit strange. Anyone has an advice what to 
do? Thx.

Regards.
