Omeka, MAMP, Zend install error

I am trying to install Omeka locally on a Mac running OS 10.6.7 and MAMP 1.9.6. The MAMP install works correctly and I can get to the "Omeka Installation: Configure Your Site" page. But when I fill out the form and click on "Install," it times out with an error message: Fatal error: Maximum execution time of 300 seconds exceeded in ... /omeka/application/libraries/Zend/Validate/StringLength.php on line 212. As you can see, I increased the execution time from 30 to 300 seconds, thinking that was the problem, but am still getting the error message. Any help would be most appreciated!

Not entirely sure what your issue is here.

Omeka definitely runs fine on MAMP. I do notice that there's a available, it's possible that there's some bug fix in that version.

Other than that, the only thing I'd recommend out of nowhere is switching the PHP version you're using. Omeka works on 5.2 and 5.3, but if there's some issue with one version in your MAMP install, the other might still work fine.

Thanks for you brilliant flash of insight "out of nowhere," John. I switched the PHP to 5.2.17 and unclicked "Zend Optimizer" in MAMP and was able to complete the Omeka installation successfully. Thanks again!
