this cometchat fully integarted with SE 3.17 , 3.18 , 3.19 ( tested and working 100% )

i solved 3 issues :

1- SQL integarting issue with SE above versions ( u will see the sql’s in config.php in line 190 ).
2- friend logout ( session ) issue .
3- cometchat link to user profile using the htaccess

all u need to do ( by the way i included the templates, htaccess, images files in the archive )
1- copy all the file / folders to the root of your testing SE site ( Backup , Backup )
2- then point ur browser to path/to/SE/site/cometchat/install.php after editing your DB and the configs as u need in Config.php …. just until the script insert the tables in ur DB
3- No need to copy the js , css to ur templates ( unless u know what u r doing

)
4- lunch ur SE Site and enjoy Sharing Exp.
