How to restart installation?

Hey all, I’ve run into a handful of errors with installation and am finally returning to trying to fix it… but now the installer won’t let me start step 2! I get a generic “the gibbons have escaped” error page and this my php error log:

One note is to restart installation - how do I do that? I tried clearing cache/cookies and it threw the same error. Is there something else I’m missing?
