As seen here, since I updated my board software to 1.8.29 no embedded Tweets appear in posts, going so far as to hide the entire post contents. I checked the MyCode and it functions fine there so I don't know what's causing it. Here is the MyCode for reference:

<blockquote class="twitter-tweet" data-lang="en" style="text-shadow: none!important; max-width: 100%!important"><p lang="en" dir="ltr" style="text-shadow: none!important;"><a href="$1" style="text-shadow: none!important;"></a></blockquote>

<script async src="//platform.twitter.com/widgets.js" charset="utf-8"></script>

I don't think it's the software update itself because another board I go to isn't having this issue.

See this guide: https://docs.mybb.com/1.8/faq/errors/#pa...ion-failed

It is a known issue since 1.8.27 due to a security fix in the post parser. There should be some error log output that may help you identify what is causing it.

Hi,

I have the same problem since updated to 1.8.29...

@Matt : thank for you link, he advice to changing the $output_validation_policy value from VALIDATION_REQUIRE to VALIDATION_REPORT_ONLY in inc/class_parser.php, but that doesn't change anything: the contents of the tweets are still not displayed..

From ACP, in test's function of MyCode, it's okay...

I enable Error Logs on my MyBB, and the error.log :

But i'm not idead that why i have this errors...

Try using this for your MyCode Lozar. I switched to this and it fixed my issue:

<blockquote class="twitter-tweet" data-lang="en"><p lang="en" dir="ltr"></p><a href="$1"></a></blockquote>
<script async="" src="//platform.twitter.com/widgets.js" charset="utf-8"></script>

I don't think it's the software update itself because another board I go to isn't having this issue.

Hello,

I have same issue ; I tried to put the MyCode you mention. It's better as the entire post is not hidden anymore. But the tweet is not displayed, I only have an empty frame.
I tried to have a look at you board, it seems to be the same (or it's because I'm not registered?)

A </p> is missing between </a> and </blockquote>

Yes. And the https in front of //platform.twitter.com

But I had already changed that, I thing this afternoon there was restrictions on the internet access I was using. Now everything is OK, thank you for your help.
