 * Hi, I use your plugin on 2 or 3 sites, recently the websites have many issues
   and the errors that appear in the logs are related to math captcha. It’s like
   hundreds or thousands of times per day. I don’t want to change to other plugins
   because I like your plugin best, but if you’re not going to fix these, I might
   just find something else. Please at least tell me if you’re going to fix these,
   or if there is any workaround.
 * 
   These are the warnings on the first website:
 * [08-Jan-2023 16:13:19 UTC] PHP Warning: The magic method Math_Captcha::__wakeup()
   must have public visibility in /home2/sitename/public_html/wp-content/plugins/
   wp-advanced-math-captcha/wp-math-captcha.php on line 86
   [08-Jan-2023 16:13:25
   UTC] PHP Warning: Cannot modify header information – headers already sent in /
   home2/sitename/public_html/wp-content/plugins/wp-advanced-math-captcha/includes/
   class-cookie-session.php on line 46[08-Jan-2023 16:13:25 UTC] PHP Warning: Cannot
   modify header information – headers already sent in /home2/sitename/public_html/
   wp-content/plugins/wp-advanced-math-captcha/includes/class-cookie-session.php
   on line 49The second website has the same warning, it’s like flooding the server
   with thousands of these warnings everyday:
 * [10-Jan-2023 19:23:14 UTC] PHP Warning: Cannot modify header information – headers
   already sent in /home/anothersite/public_html/wp-content/plugins/wp-advanced-
   math-captcha/includes/class-cookie-session.php on line 46

   in /home/anothersite/public_html/wp-content/plugins/wp-advanced-math-captcha/
   includes/class-cookie-session.php on line 49Thank you!Regards
