500 internal error solves only after disabling cache

hi

I am using MODX Revo vers 2.1.3-pl and have been having problems with 500 internal error page at both backend and front end sides pretty often
now, the only solution which looks to be solving this issue, was disabling all cache items in system settings
this is not the first time I'm raising this issue and got several valuable feedbacks from other developers from which one was that of the hosting might be running out of free space and this would be one which causes this error
however our hosting provider let us know that this problem is out of question since there is no any limit on disk space

our problem is, that by disabling the cache, the websites loads much slower than previously

so, I would appreciate if someone would guide us or let us know his opinion what might cause the 500 internal error when cache is enabled

thanx in advance

Generally this is going to be caused by a Plugin or Snippet that had code which is dependent on something that is perhaps not available when run from a cached copy. It could also be a problem with the hosting environment, but you'll have to provide details for us to be able to pinpoint the specific problem.

thanx opengeek
you are most probably right, this is what we also think
now, I'm just thinking about which way would be more efficient to test all snippets, meaning to filter out the one which might have the code dependent on something not available from a cached copy

any suggestion?

Try disabling tags in the content until you get a non-blank response. An easy way to do this is to put a space in between the two brackets, e.g. .

FWIW, in MODX 2.1.4/2.2.0 you can use a - token after the opening tags to have a tag ignored — this is the new comment tag syntax.

sorry opengeek for my late response

thanx, I find your reply very valuable
