Hi,
this morning after the last update it is not possible to use the panel.
on port 2199 the answer is:

"_il_exec failed"

Before the upgrade (with the version of last friday) it works everything fine.

What happen?

Server is a clean Cento6

We're aware of this and will be pushing out an update for it later today.

Update didn't help

Confirmed and fixed.  Run /usr/local/centovacast/sbin/update one more time, then restart Centova Cast (/etc/init.d/centovacast restart) and you'll be good to go.

Ok, now the problem is resolved and can login to the panel.

Another Issue:
The media library page doesn't work after upgrade.
I can create account, upload the files on "file" like usual, can edit and create playlist,
but if you click on "media" nothing happen. The page is blank (with template).
Try to purge the cache. Nothing.  Try with Safari, firefox & chrome.
On every page it seems not end to load the page completely. the symbol of the page load is always running.
On IE8 the panel chrash every 5 seconds.

All was working fine till the version of last friday. Probably problems with new fastCGI

Still doesn't work...
The panel web interface it works bad after the upgrade.
No way to load every page to the end...
The media library still not visible on all browsers (mac and windows).

Everything works for me after update so that maybe Your system related problem

Solved.
My network admin closed for error ports 2196 and 2197.
After open them, it works all fine.
