Hi, I'm sorry if something easy and basic is happening, I'm a super beginner. I recently made a petition with speakup for my website. Everything was working fine and then the next day, I installed the Polylang plugin to start making my site multilingual. However, after installing Polylang, people were no longer able to sign the petition and got this error message:
Fatal error: Call to a member function switch_lang() on a non-object in /home/imocha1/savejejuisland.org/wp-content/plugins/speakup-email-petitions/includes/ajax.php on line 14
Although I suspected a conflict with Polylang was a problem, I de-activated it and re-activated it several times to check. When it was inactive everything was fine and when it was active i got the above error.
Can you please help me understand the problem and what I can do it fix it? I really need to use both plugins.
