White Screen

[zarahel]

Good afternoon to you all

I have a fresh installation of Cacti 0.8.7 d and Plugin Arq 2.4

But as soon as I add the lines in config.php, when I try to access my cacti page all I get is a white screen:

$config['url_path'] = "/cacti/";
$plugins = array();
$plugins[] = 'monitor';
$plugins[] = 'weathermap';
$plugins[] = 'syslog';
$plugins[] = 'settings';
$plugins[] = 'dataquery';
$plugins[] = 'reportit';


What´s wrong here?

Backout all your plugins and get that working first. Then, add them one at a time. Remember PIA 2.x plugins work differently.

First of all, you should be adding that to global.php, not config.php. The location changed once 0.8.7 was released.

I am having the same problem. Just upgraded to 8.7d (which went fine) I then tried to install the new PA (cacti-plugin-0.8.7d-PAv2.4-1.tar)... and I am getting the white screen. There were not installation instructions with the new PA so I followed the instructions on the documentation page...

I noticed in my httpd log the following errors....which make reference to a "functions.php" file with I dont even have in my include directory....

I also see a bunch of posts about PA.sql and importing it into the database... but there were no .sql files as part of the PA installation package. I figured this to be an easy upgrade but alot of people seem to be having issues with it. I had a tough time just finding the tar.gz format of the PA... Are there any descent installation instructions with this new PA?

[cigamit]

Permission denied

Thats your main issue.

There is a pa.sql file included in the Plugin Architecture download.

[kbartoletta]

Maybe that is part of the problem... Do you have a link to the .tar.gz PA installation files. All I could find on cactiusers.org was the .zip. I found reference to a .tar.gz version in another post but there was no .sql file in there.

[cigamit]

I didn't make a tar.gz version this time around. I re-downloaded and double checked the zip, and the pa.sql file is in there in the root where the patch itself is.
