Someone please help, my website just totally became inaccessible to me after I installed the bbpress forum plugin. I just wanted a few more options for the search widget and tried to activate a plugin for this but it said I needed to have the bbpress forum plugin installed before I could activate it. I installed it and now I can't navigate away from the page you see after the successful installation of a plugin.
When I try to navigate anywhere, even the plugins page to delete the problem, it sends me to a white page with this text
Fatal error: Call to undefined function deactivate_plugins() in /home3/insignia/public_html/wp-content/plugins/bbpress-forum-redirect/bbpress-forum-redirect.php on line 250
This is my first website and I have spent the best part of 4 weeks building it and learning. I can't lose it, I was just complete with my design and layout and the search widget was literally my final touch before adding my content. This was literally the last plugin I was likely to get.
Please can anyone help me? I need help fast
