Mamp Pro 4: Apache won't start

Question

I used Mamp Pro 4 for a while with no problem on my Mac (Os X 10.11), then, suddenly, Apache won't start. I got an error: "Check the log" but log is empty.

I have made several test:

• reinstalled Mamp Pro 4 (4.0.6);
• rebuild permissions using utility disk and Onyx
• update Mac os X El Captain to Sierra;
• started Apache/MySql as "www" or as "user"

Note:

• 1) starting system Apache it works
• 2) using MAMP (not pro) Apache works fine.

Any other suggestions ? Thanks

Answer 1

Fixed!! The issue was in SSL. For some reasons it stopped to works. No logs and no warning occurred: just an empty log. I deleted the SSL and created a new certificate. Now Apache works fine as well.

Answer 2

Have you tried to force-quit apache? I got this issue sometimes as well and using the terminal-commands sudo killall httpd and sudo killall mysqld fixed this issue.

Sometimes I have to repeat the commands a few times.

Answer 3

Upgraded to mamp pro 4.2.1. Now apache won't start. followed directions here: https://appsolute.zendesk.com/hc/en-us/articles/215197286 Nothing in activity monitor. Nothing in log file.

Resolved by deleting hosts in mamp pro, where the document root had been deleted.

If you are seeing a red circle-arrow next to the Hosts link in the upper left, find the hosts that are not resolving properly to a document root, then fix them or delete them. That resolved it.
