Deprecated in 1.7: extend_view() was deprecated by elgg_extend_view()!

Hi everyone.

I'm getting this error on my elgg install :

Deprecated in 1.7: extend_view() was deprecated by elgg_extend_view()!


It can appear while posting, or even refreshing, but not always. The site worked like 3 monthes without having this once, and now this error message pop sometimes.

Can someone help me ?
