SharePoint 2010: Application Pages Throwing Error

Question

I am facing very strange issue. I have created a site template from a site which has simply Wiki Pages, Lists and Libraries. Lists are using some Content Types which already exist in parent site.

I can create a site using that template, it creates successfully, work well but application pages like settings(_layouts/settings.aspx), permission, etc. pages are throwing "Unexpected error occurred".

FYI: I am not using Publishing pages but few site at top level are using Publishing feature.

Please help!

Thank you,
Amit

This forum post was helpful and I resolved my issue.

The issue was due to alternate css I used. Here are the steps that I used to fix:

Step 1: Reset to default CSS so that template won't include alternate css file:

Site Actions > Site Settings > Master Page

Alternate CSS URL:
Select option: Use Microsoft SharePoint Foundation default styles
Check : Reset all subsites to inherit this alternate CSS URL
Hit OK

Step 2: Create site template
(This template will work fine now)

Step 3: Set back to your alternate CSS from Master Page settings
