AdsManager / 502 Proxy Error??

When I enable SEO in Joomla GlobalConfig, I get 502 Proxy Error. When is SEO disabled - no proxy error.

Whats wrong?

thanx

Most likely, you will have to check in your server confguration - if you are using proxy, its content may need to be refreshed when SEO is activated.
Also, there might be some issue in configuration when using combination of proxy + mod_rewrite.

1. I would try to disable proxy usage and test if it works
2. switch proxy back on and test again; if problem occurs, probably some server configuration tuning will be needed
; this is however most likely job for your server admin

Funny is that I am not using proxy.

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /index.php.

Reason: Error reading from remote server

Well, so where does this error come from? Is this server-like or joomla-like error?
I guess the server where your site is located may be behind proxy without you being aware of that.

Mostly, proxies work transparently, so users do not even realize there is some. If it works right.
I am afraid I will not be able to help you much on that, but I think your server/network administrator might have some ideas as he should know the configuration.

Yes, you were right!
My server admin resolve it - just turned off eaccelerator

Thanx!
