Upgrade issue on IIS

[Konstantin Alexandrov]

I had Jira 7.3.3, yesterday I upgraded it to 8.0.2 but I can't make it work.  I tried reinstalling 8.0.2 and restarting my server, nothing helps.

It's a windows 2012 server, iis 8 or 8.5

I use a connector like for 7.3.3. 
<Connector port="8080" relaxedPathChars="[]|" relaxedQueryChars="[]|{}^&#x5c;&#x60;&quot;&lt;&gt;"
                   maxThreads="150" minSpareThreads="25" connectionTimeout="20000" enableLookups="false"
                   maxHttpHeaderSize="8192" protocol="HTTP/1.1" useBodyEncodingForURI="true" redirectPort="8443"
                   acceptCount="100" disableUploadTimeout="true" bindOnInit="false" scheme="http"
                   proxyName="tasks.inoclub.ru" proxyPort="80"/>

Sometime it loads but then it works very-very slowly - a page load takes 2-3 minutes (no matter if I start it locally using localhost or remotely using a domain name).

I see the following issue info:

Hi @Konstantin Alexandrov , it looks like this is an error in the code, it is suggested here to restart the server and do a full re-index.

After you are logged in the system try to review each system add-ons and double check if there is a disabled add-on and re-enable it.

- 

Another workaround is to remove the index and rebuild it again.
