While working on one cPanel server we could see below error in error_log file for one client
libMagickWand.so.2: cannot open shared object file
The error log were filled by such errors
reinstalling imagemagick using command /scripts/installimagemagick didnt work as error were still persisting .
So renamed the php,ini file
mv /usr/local/lib/php.ini /usr/local/lib/php.ini-old
Now to regenerate the new php.ini file I had to use command
A new PHP.ini was create with default entries like a newly set server.
Modified the PHP.ini to customize it as needed
Then had to finish it by rebuilding apache and php using easyapache
Now all sites work fine without any error 🙂
