 * Hi everyone,
    I use Elementor Pro and wanted to change some minor things on my
   website this morning and got a ‘cannot modify header information – headers already
   sent by’ warning. Elementor didn‘t work and since I wanted to redesign my homepage
   anyway I decided to reinstall WordPress. Reinstall was done but when I tried 
   to activate a theme or plug-in I got some fatal errors and WordPress stopped 
   working. I uninstalled it again and deleted all the files in my public_html folder(
   with CPanel) and reinstalled, but the problem persists. Can anyone help me out
   with a solution or advice on how to find out what’s causing the problem?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fproblems-with-wp-after-reinstall%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * My browser says http500 error. When I refresh and try to click something in the
   dashboard I get the standard wordpress ‘critical error, a message is being sent
   to your email…’ message. I know these emails contain useful logfiles but I never
   got any.

   41943040 bytes exhausted (tried to allocate 20480 bytes) in /home/hypszlhw/public_html/
   wp-includes/widgets.php on line 644

 * Yesterday I ran the debug mode in my wp-content.php and found the error. The 
   memory limit wasn’t high enough for some reason. That’s weird since I never had
   a problem with the memory size, not on any of my many homepages. I unlimited 
   the memory size by -1 in my php.ini and now everything seems to be working nicely.
   Thanks again! 🙂
 * Edit: totally forgot that I already sent the error message before 😀
