Error encountered while writing /includes/configure.php - database setup

I have searched and read the other threads but they didnt seem to help,
Im getting this error on the database page of the installation.

The thing is when i download the configuration page to check it it has written everything to the page, so Im unsure why this error is occuring if it has managed to write to the page?

After hours of headaches and searching these forums to no avail, I have finally gotten past this error.

What I did is to go back to the "System Setup" page in the installation and changed the referenced "Physical Path" to "/var/www/html/ZenCart", where I also had a full copy of ZenCart. Previously I had referenced a copy of ZenCart in a user directory under /home , since I had wanted that particular user to administer the ZenCart. Apparently putting ZenCart in a user's home directory is a no-no. It seems as if it can only function if it is under /var/www/html/ .

Prior to doing this I had also chown-ed both ZenCart directories recursively to be owned by user apache and group apache, since they had aquired root ownership from the way I ftp'ed them. I don't think this should be necessary because they were mode 777 anyway and that step didn't solve the problem. Just mentioning it in case someone can't replicate my success and it turns out to have been a necessary condition.
