Cacti 0.8.8a plugin shows a blank page

[gueroh]

Hello Everybody,
I'm running Cacti 0.8.8a on Ubuntu server 12.04 precise. I've used the repository for 12.10 to install 0.8.8a version.

I've installed the plugin setting successfully. I've also installed thold. Everything seems fine and the Tab thold is shown correctly. However if I click on it, I can see just a black page with nothing on it. The same thing if I use the left menu for the threshold.

Any advise is more than welcome.

Thanks,
Cristiano

Check apache logs.

Delete this line and everything will be fixed

I have the same problem after upgrade to 0.5 i just get a blank page. I have the following errormessage in the apache logs.

PHP Fatal error: Maximum execution time of 30 seconds exceeded in /var/www/html/cacti-0.8.8a/lib/adodb/drivers/adodb-mysql.inc.php on line 479, referer: http://cacti.xxxxxxx/

Cacti: 0.8.8a
PIA: 3.1+
Settings plugin: 0.71
Thold Plugin: 0.5

I have tried to do a uninstall and reinstall of the plugin with no success.

I don't know if you solved the issue, but here is the solution:

Basically uninstalling the plugin and commenting:
#db_execute("ALTER TABLE thold_data REMOVE COLUMN bl_enabled", FALSE);
#db_execute("ALTER TABLE thold_template REMOVE COLUMN bl_enabled", FALSE);
in include/database.php

I'm not responsible if you lose any settings*
I had a clean install and that's what worked for me.
