Cache Media Error

Describe the problem you’re having:
My Event Log is being flooded with the following:

Error: E_WARNING (2)
Filename: classes/rssutils.php:1268
Message: DOMDocument::loadHTML(): Empty string supplied as input

  1. classes/rssutils.php(1268): loadHTML()
  2. classes/rssutils.php(833): cache_media(, website.url/)
  3. classes/rssutils.php(153): update_rss_feed(98, 1, )
  4. update.php(252): update_daemon_common(50)

I have enabled caching media in this feed, but I only actually pull the inline images with Af_Readability inside a filter. I’m sure it’s the empty (bare) feed that’s causing the error, and I’d also bet that it’s a badly formatted feed in the first place. However, is there anything I can do to mitigate or eliminate the errors from showing up?

while this particular warning might not be necessary, you don’t need to run for the hills (or this forum) in panic just because there’s a new message in the event log. it doesn’t mean something is wrong.

I understand that this message is not significant. However, my event log flooded with hundreds of these messages does make it impossible to find/notice any warnings I should be aware of.

You can always do what I do: Dump the output to /dev/null. I only put logging on for TT-RSS when I notice something not working.

(With proper log rotation, etc. setup it shouldn’t really matter anyway.)

yeah, it was more of a general comment on the event log. i’ve made a note to take a look at document-related warnings (including this one) when I have some free time. :slight_smile:

Thank you both!
I’ll go ahead and redirect the output for now while I wait for something more permanent down the road.
