Answered No installation possible: mod_fcgid: stderr: PHP Fatal error:

Hi,
i just downloaded modx revolution 2.3.1-pl and wanted to install it from the scratch on an ubuntu 14.04 / ISPConfig 3.0.5 server

----------------------------------------------------------------------------
Setting up the homepage, install DB-User and DB went fine:

Connecting to database server: Success!

- Checking MySQL server version: OK! Running: 5.5.38-0ubuntu0.14.04.1
- Checking MySQL client version: OK! Running: 5.5.38

Checking database: Success!

Default Admin User

Now you'll need to enter some details for the main administrator account. You can fill in your own name here, and a password you're not likely to forget. You'll need these to log into Admin once setup is complete.

But after pressing "install", i get a white screen and the apache2 error message in error.log:

[Tue Sep 23 14:20:37.844869 2014] [fcgid:warn] [pid 27816] [client x.x.x.x:37403] mod_fcgid: stderr: PHP Fatal error: Can't inherit abstract function modDashboardWidgetInterface::render() (previously declared abstract in modDashboardFileWidget) in /var/www/clients/client1/web13/web/modx/core/model/modx/moddashboardwidget.class.php on line 117, referer: http://www2.pixelbunker.de/modx/setup/index.php?action=summary


What can i do? i have no clue...

How did you upload the files before installation? Quite often if you uploaded the unzipped files via FTP there will be missing or corrupted files. It's recommended to upload the .zip file, and unzip it and move the files into place on the server.

i uploaded the zip.file and extracted it with an unzip php script.

btw: modx evolution installation is no problem, but i think that does not matters this here

hmm. now i get an error 500 with the following output in error.log of the domain:

[Tue Sep 23 17:00:58.793900 2014] [fcgid:warn] [pid 32523] (104)Connection reset by peer: [client x.x.x.x:48722] mod_fcgid: error reading data from FastCGI server, referer: http://www.mydomain.com/setup/index.php?action=summary
[Tue Sep 23 17:00:58.793960 2014] [core:error] [pid 32523] [client x.x.x.x:48722] End of script output before headers: index.php, referer: http://www.mydomain.com/setup/index.php?action=summary

26 tables are build in the SQL database. modx_site_htmlsnippets is the last one in the list.

Hm. Sounds like a PHP/FPM - nginx configuration problem. Those can be nasty to track down.

no nginx. apache2 is installed with the following virtual host entries in isp-config panel:

su-exec is active and fast-cgi

Well, I know even less about that, so I'm out

Ok. after 3 Days of investigation, i got it.

Disabling Optcache in the Options of the website does it.

Custom PHP.ini settings: opcache.enable=0

I think the problem is the flushing of the cache with too much data in the install process. Because of that i got various error messages and the error

"End of script output before headers: index.php"

gave me the hint i needed.

Now i can go to the login page

in ispconfig /website/options put this in custom php.ini settings: opcache.enable=0

that disables the cache module and the installation goes flawlessly, shiny and pretty

the trick in ispconfig to disable the opchache in the php.ini does the trick for me aswell. Thanks for the hint!

btw. also opcache=0 on various othe cms systems. i disabled it now by default.
