Hello, I get the 500 internal server error when I try to access the items menu in K2.

First, I installed K2 and it appeared as K2.con, or something like that, in the component menu and I got the internal server error on everything. I uninstalled K2 by searching for all components that contained "k2" and then reinstalled it. Now, everything seems to work except when I try to go to Items.

I searched "500 internal server error" and saw a lot, but not the exact same problem. I noticed the advice was to turn on the error log, but I am unable to find that.

Any help will be greatly appreciated.

500 server error is the most annoying error to troubleshoot since it can be anything. It really means that 'something' caused an error on your web server and the server logs should tell you what it is. if you are not familiar with checking out the server logs, note down the time you saw the error on your site and ask your hosting provider to send you the extract of server logs for that time period. You need to take a look at Apache log, php log and mysql log. That will tell you what the reason was.

Thanks, but the problem seems to have resolved itself.

Here is the last time the error occurred, as reported by the Mac's Console:

12/20/14 8:13:27.175 AM Safari[56691]: Failed to save record: <CKError 0x608001a58ae0: "Internal Error" (1/5001); "Fetched zone had no protection data: <CKRecordZone: 0x7f8a1e7442c0; zoneID=History:__defaultOwner__, capabilities=(Atomic,Sync)>">

hmm... not sure if its Safari related or something else. The error message doesnt help much. Anyhow, glad it works now. If it happens again see if it opens in other browsers.

Thanks again. I had forgotten to mention that I had also tried it in Chrome with the same result.

Anyway, hopefully all is well going forward. I'm making a backup of my site before importing the articles into K2, just in case.

This error is more likely a JS error.
You need to enable error reporting and set it to Development in your site's global configuration to see the actual issue.
