I tried to use page_title in views (without any success for now) so I made a display in a view with the page_title option. Because I failed to make it work, I've deleted this display, and left my view has it was before my test.
Since then, when I go on pages made by views, I got this srtict warning :
Strict warning : Only variables should be passed by reference dans views_page_title_pattern_alter()(line 33 in /sites/all/modules/page_title/modules/views.page_title.inc).
Anyone has an idea from where it can come from ?
Maybe must I delete something in the DB ?
Thanks for your help.
