d 7.4.2 stock problem CHAT NOT WORKING

using the latest version of PHP (x 64 7)

and latest APACHE and MYSQL

I am getting major errors in the old FLASH CHAT!

bought some mods to install to fix it and even those do not work.

does anyone know how to get CHAT working????

maybe a php extension file or some setting in php.ini ???

RAYZ tried fixing it. he said there were so many mysql errors. but it is stock Dolphin 7.4.2

and it's on PHP 7 and full of errors. the rest of the website works fine.

can anyone help?? its important that chat works for users to communicate with

Then I suggest going back to 7.3.5 with php 5.6.x if that is possible.  What did Dolphin 7.4.2 offered that you had to have?  If the answer is nothing, then go back to 7.3.5.
