Administration link missing after installation, can't log in at all

Hey guys,

I've tried to install nopCommerce 2.5 on our server the same way I did already 4-5 times before without a problem, but now I can't log in at all after installation.

IIS6 server | MySQL 2008 database with all the writing and reading eligibilities set | nopCommerce 2.50 no source installer

..First it was also weird that after installation started I get the 'Service unavailable' error message, but a simple refresh helped. I thought okay, that can happen, but to be honest it happened to me a couple of times now while I was trying over and over again.. So after installation page loads, but the link for administration is simply missing totally on the page, and registration doesn't help me at all, because after reg I still face the problem with the missing possibility of the administration.

I made no changes to the settings.txt file nor any changes on the server. Related files checked on FTP and no lines of code were missing. (yeah, well I had no idea so checked them)

Any idea what could cause this to happen? Of course v.2.60 is not the solution this time, customer needs to use 2.50.

Thanks in advance for any kind of helpful advice! Cheers

It could be caused by a slow installation process in 2.5. See this topic for more info. This issue was fixed in 2.60.

Thanks, for your response, but actually it seems the issue is the same with the 2.60 version, as I've tried this already. Nevertheless I'll run few checks on the server this afternoon and come back if it does tha same again. Thx again!
