After recent upgrades (Joomla 3.7.0) and Easyblog we are unable to make edits or add posts from the frontend and the backend is going REALLY slowly. The frontend error is:

0 - PHP regular expression limit reached (pcre.backtrack_limit)

We also upgraded to php7 but had to roll back to 5.6 because of an issue with EDocman which we also use but ideally will revert to PHP7 again once this is resolved.
Hello Simon,

This is actually a known issue on Joomla 3.7.0 and it really isn't an issue with EasyBlog. You will hit similar problems if you are composing a large set of data on Joomla articles.

You can learn more about this on https://github.com/joomla/joomla-cms/issues/15673

I believe this issue is already fixed in Joomla 3.7.1 but we'll see how this goes when they push the updater later today.

Okay thanks, will see how it goes then later today when we push out the update.

Can you clarify what you mean by composing large sets of data in the article?

Hello Simon,

When you submit a form (data) to the server, we actually retrieve the data via Joomla's "request" api as it sanitizes the data that is being sent to the server. However, this process has a bug as addressed on https://github.com/joomla/joomla-cms/pull/15966

By the way, you should update to 3.7.1 as soon as you can because that is a critical security release.
