Ok guys I got this issue sorted.

the table "guest_info.MYI" had somehow gotten corrupted.

in order to fix this I went to my server and connected to it VIA SSH

then logged on as the ADMIN.

this can be done by typing "su" and then entering your admin password when prompted (after logging in as a regular user)

Then I logged into mySQL
mysql -u admin -p databasenamehere
then entered the password when prompted
Then I moved to the folder / directory on my System that housed the mysql database and ran this command

myisamchk --recover --quick guest_info USE_FRM
Caution
Do not use USE_FRM if your table was created by a different version of the MySQL server than the one you are currently running. Doing so risks the loss of all rows in the table. It is particularly dangerous to use USE_FRM after the server returns this message:
