Server error on new install OC 9.1.3

I downloaded the latest version of OC (9.1.3), uploaded it to the server, created a mysql database and ran the install.
At the end of the install a page returns the following error
Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

So I checked and found that the new database had been populated with the tables and the Admin user added - it's just the main page will not load.

Can anyone advise me on what the problem may be?



I re-ran the installation and this time tried using the SQLite database.
The installation began and when complete if I access the pages I see an error stating problems with the code integrity check followed by a statement saying 'Problem loading page - retrying in 5 secs'.

I have tried re-uploading the complete OC package and re-running it - same problems occur.

Any help would really be appreciated.
