Anyone have this after updated to 32.0.6 ?
PHP Imagick module
The PHP module “imagick” in this instance has no SVG support. For better compatibility it is recommended to install it.
I have already install php-imagick and apt-get install libmagickcore-6.q16-6-extra
It’s on newest version and no matter how I remove and reinstall imagick this message still there ?
PS : I FIXED IT , for anyone who just updated nextcloud 32.0.6 and got this warning message , Just install the PHP Imagick extension , please check this link below
