Thank you so much for the suggestions. I checked config.php. Instead of dirroot, it has wwwroot. It points to the right directory. Should I change 'wwwroot' to 'dirroot?'
lib.php existed where you said but the file was empty. I ftp'd the file to the proper place. Now I get this error upon trying to run install:
Config table does not contain version, can not continue, sorry. Coding error detected, it must be fixed by a programmer: block_manager has not yet loaded the blocks, to it is too soon to request the information you asked for.
Do I have to re-set anything to try the install again? Thoughts?
