* Hi there
* Thank you for creating what looks to be an incredibly useful plugin, that will
be helping many folks with CSP-related headaches!
* When I enable tag capture, our website crashes with a ‘HTTP ERROR 500’ message.
From a lot of trial and error I established that removing this ‘show_content_snippet’
function from functions.php stops the crash happening, but it is pretty crucial
to our site working properly. Do you have any ideas why this would be interfering
with your plugin? Many thanks!
* */ function show_content_snippet( $post, $amount = 100 ) {
$post = (array)$post;
if( $post[‘post_excerpt’] !== ” ) {echo apply_filters( ‘the_excerpt’, $post[‘
post_excerpt’] );}elseif( preg_match( ‘##is’, $post[‘post_content’] ) ) {$moreSplit
= explode( ”, apply_filters( ‘the_content’, $post[‘post_content’] ) );echo $moreSplit[
0];}else{echo ” . substr( strip_tags( $post[‘post_content’] ), 0, $amount ) .‘…’;}}

* It appears in about 8 php templates, like search.php, index.php, archive.php
and the home page template to show a short text excerpt
* e.g. [https://www.tsl.com/?s=MC67](https://www.tsl.com/?s=MC67)
* ```wp-block-code
```

* Hi @Jameth, i have tested your function in a couple o standard themes, and it
doesn’t create any error if capture is enabled or not.
* Can you try to extend the amount of memory allowed in your php.ini? Do you have
any server report of the crash?
* Maybe it’s just a typo, but I think there is an error in your code:
* i guess that
* `$moreSplit = explode( '', apply_filters( 'the_content', $post['post_content']));`
* should be:
* `$moreSplit = explode( ' ', apply_filters( 'the_content', $post['post_content']));`
* For me your code generates an error:
* Uncaught ValueError: explode(): Argument #1 ($separator) cannot be empty
* But this is completely unrelated to No unsafe-inline

* Apologies for the late reply, and thank you for your help! I did try extending
memory limit but still experienced the same crash. I also checked the error log
file but couldn’t see anything being reported at the time of the crash. I’ll
do some further tests to make sure I haven’t missed something.
* Thank you for pointing out the unrelated error, thats very kind of you. We will
look further into that.

* Hi [@jameth12](https://wordpress.org/support/users/jameth12/), please test the
development version of the plugin and tell me if the issue is still present.
* The new version should spare some memory when protection is enabled; however
the new code has to be considered experimental until the new version will be
released.

* Thank you, but same crash with the developer version unfortunately. Learning
as I go, the error logs within CP File Manager weren’t the right ones to be looking
at, I needed to be looking at the latest error messages at a higher level in
cPanel tools. It shows a handful of logs all with identical content, here’s one:

* Nice shot!
* What happens here is that your page contains an invalid url in the src property
of a `
* I will fix the code, because the plugins should not crash when it finds an invalid
url but simply it should not process it, however I think you should fix your
page.
* The bug wil be fixed in next release.

* The tag capture is working now! That invalid URL was being generated by an incorrectly
enqueued script within functions.php.
* Thank you so much for your help and for pinpointing the issue!
