Something to consider when people are reporting problems might be the web host. I have installed on two different sites, with different hosts, and one of them has been a source of significant problems.
IPowerWeb is the host that has caused me the most problems. I am documenting some of as they arise. When using the MySQL container, the table parameters will not work. The largest index I could create on that table was 500. I resized the varchar fields to a corresponding 125. Also, the create table will only work on an existing database - databases must be created through the V-Deck Panel. Also, the table must be type MyISAM. That's ok for me on a low volume system, but it kills performance.
I have never been able to run a chmod command from a script on any IPowerWeb server (I have 3 sites with them).
They have multiple servers, not all configured exactly alike. I think I am on the bottom rack
On another host I have had no significant problems at all.
