Hello everyone. This is my first post so i apologise if i am posting in the wrong place or if i break some protocol. Also english is not my native language so sorry about that too. I don't know if this is already posted but i hope it helps someone because it took me a while to find it out. I followed the "the perfect server" tutorial for Ubuntu 16.04 inside an Azure VM. After a couple days someone asked me to increase the upload file size. I inmediately went to the apache2 folder and modified the php.ini file but i didn't work, didn't work also for the php.ini inside the cli, fpm and other folders. Anyway, i tried several things and, in the end, i made an experiment (Since i don't have advanced skils in programming). In many places said that you should increase the upload_max_filesize parameter inside the .htaccess file in /etc/roundcube. I did it but it doesn't work. Then i noticed that the module inside the file says: <IfModule mod_php5.c> But i had installed php7.0 from the tutorial. I tried changing it to <IfModule mod_php7.0.c> didn't work either... finally i tried <IfModule mod_php7.c> and everithing worked perfect, now i can atach files up to 50MB i hope it helps someone, bye. PD: I tried with no success to install aditional php versions following tutorial: https://www.howtoforge.com/how-to-u...fpm-and-fastcgi-with-ispconfig-3-ubuntu-12.10 But i had touble with the repositories or something related to the 16.04 version, when i have more time i will try ir again and maby post if something interesting comes out.
