I have been running MAMP Pro 3.05 successfully in Yosemite up to DP4 on a partition that was a clean install of Yosemite.
I now have run the installer for DP5 over my Mavericks install, and now that MAMP Pro install will not start Apache. It says to check the logs, but I don't see anything pertinent.
I'm assuming that since this is a pre-existing install, something in its config is wrong for Yosemite's Apache.
Any ideas?
