upgrade Error V7.3

I have this problem when I want comments on Friends. I can not get this error. bad comment parent id  and and down comes this
Please enter 3-2048 characters. Please help

This problem can occur when you place timeline/wall and comments on the same page. Only one block - comments or timeline/wall can work on profile's page. Actually comments functionality exists in both of this blocks, so it make sense to have only one of these blocks.

there is only one timeline on last version was working fine but on this version7.3 doesn't

I found the problem for people who have the same problem

in INC/classes/BxDolCmts.php on line 126 edit

'CmtText'     => array ( 'reg' => '^.{3,2048}$', 'msg' => str_replace('"', '\\"', trim(_t('_Please enter 3-2048 characters'))) ),

to this

'CmtText'     => array ( 'reg' => '^.{0,2048}$', 'msg' => str_replace('"', '\\"', trim(_t('_Please enter 3-2048 characters'))) ),

There are two identical lines. Please could you reproduce the problem on demo.boonex.com ?
