Error 500 on Domain Settings page Miva Merchant v4.22

[mikeheckman]

I haven't needed to go into the Domain Settings area on our Miva install since we originally set it up. Now, there is a setting I need to change and when I click on 'Domain Settings' I get an 500 Internal Server error.

I've done a fair amount of searching on google and looked through the forums here, I can't really get much in the way of additional debugging information nor do I see a solution to the problem anywhere.

I'm using Miva Merchant v4.22 and Miva Engine v4.1400.
The error log shows 'Premature end of script headers: mivavm-v4.14'
The access log shows '66.47.154.24 - - [21/Sep/2006:12:50:55 -0400] "GET /miva/admin.mvc?Session_ID=ba8b0d10befd3c094270059513f38 016&Screen=DOMN HTTP/1.1" 500 1499 "http://xxxxxxxxxxxxxxxxxxxxxxxxxxxx/miva/admin.mvc?Session_ID=ba8b0d10befd3c094270059513f38 016&Screen=LNAV" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.13) Gecko/20060724 Firefox/1.0.8 (Ubuntu package 1.0.8)"'

Thanks for your time.

500 is a generic error that the Apache web server outputs when just about anything goes wrong; Miva Empresa crashes, a server resource limit is reached and it kills the store, etc. You'll likely need your host to debug what is causing it to occur on just that screen; they should be able to fix it.
