I can not upgrade to version 8.10
I followed the manual upgrade protocol and it gave me an error that stated:
concrete5 requires PHP 5.5.9+ to run so I upgraded to the 5.5.6 that was listed in my bluehost cpanel but then got an error that said: access denied
I am very new to all this and would appreciate any help you can give me.
I would be surprised if your host does not offer PHP 5.6 as a PHP option..
Might be worth reading this Bluehost instruction.
