in config/site.php

Make sure there are not any extra lines at the end or beginning.

There also appears to be a ;; in there. Maybe that is in your config/site.php.

Ah yes.

My last line of code looked like (It was all on one line):

define('CACHE_FRONTEND_OPTIONS', serialize(array('automatic_cleaning_factor' => 0)));?><?php define('DIRNAME_APP_UPDATED', 'concrete5.4.2.2');?>

At first glance I thought it was missing the ; so I added it:

define('CACHE_FRONTEND_OPTIONS', serialize(array('automatic_cleaning_factor' => 0)));?><?php define('DIRNAME_APP_UPDATED', 'concrete5.4.2.2');?>;

Thus the error.

Thanks for the help.

I'm not sure if you are doing this already but you need to make sure you are manually clearing the cache when you disable automatic cleaning. I'm attaching a job file that you can install and run once an hour/day/week depending on you site load.

Thanks. Do you have any documentation on how to install a job?

I placed the file in /concrete/jobs/
Logged out, cleared my cache, logged back in.

I don't see the job in System & Maintenance/Jobs
