Purchased and installed your chess script. It went pretty well but I am seeing/having some issues..
The first issue I came up on was an error setting the primary key when importing the database.
the alter table statement for setting the primary key to 'code' kept coming with;
Specified key was too long; max key length is 767 bytes
did some duk duking and a number of results said for utf8mb4 to change the value from 255 to 191
after doing this the database imported without error and as far as I can tell rooms are working correctly.
2nd issue is setting up mail. On my server I can use sendmail or smtp, (mail firstname.lastname@example.org
I am not sure if this is the mail functions of your script or the form processing.
if I goto -Contact us- and fill in the fields and click -Submit- under -Submit- it will say processing for about 1/2 seconds, then change to [object Object] if I don't put anything in the fields I get the same result (no validation)
Would like to get this going other than what appear to be a few minor issues this is a nice little script.
