How to delete a wall post (activity page not displayed good with a hypeWall post problem)

Hello

My site activity page suddenly not displayed. Only blank page. I check system log. I see `PHP fatal error : maximum execution time of 30 seconds  exceeded in ....  hypeScraper ...

I increase max exec time in PHP.ini to 90 seconds but no change.

Then I search for hypeScraper and I find someone say the same thing because a user on his website post a strange URL and it confuse hypeScraper or hypeWall :

https://github.com/hypeJunction/hypeScraper/issues/41

Its title say `hypewall bring entire site down` but it is not true. Only activity page not displayed. And problem go away when problem post deleted. But how delete it?

I try disable hypewall and try delete last post. I disable hypeWall and I see my activity page but only replies to wall posts deletable, wall posts not deletable (not displayed but only a line with error message hypewall plugin missing)

How can I delete a wall post in this situation?

 I have Elgg 2.3.12 hypeWall 5.2.0 hypeScraper 5.5.0

Thank you for your help.

Selen.
