Database problems?

[KchoPrro]

Hello friends, for a long time my gallery gives me an error:

Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /var/www/vhosts/adolfoventas.es/httpdocs/galeria/include/functions.inc.php:183 Stack trace: #0 /var/www/vhosts/adolfoventas.es/httpdocs/galeria/include/init.inc.php(171): cpg_db_connect() #1 /var/www/vhosts/adolfoventas.es/httpdocs/galeria/index.php(26): require('/var/www/vhosts...') #2 {main} thrown in /var/www/vhosts/adolfoventas.es/httpdocs/galeria/include/functions.inc.php on line 183

My website: http://www.adolfoventas.es/galeria/

A photo from the gallery:

I have checked everything and it seems to be in order, the database is correct, what is the problem?

Your hosting account has probably switched to using PHP7.x instead of PHP5.x.  You will either need to have PHP5.x be active again or upgrade your gallery to CPG 1.6.x.

You also need to fix your SSL certificate.

OK thanks!!. I will have to update, manually, to version 1.6x

Finally, I have spoken with my hosting provider and they have lowered the PHP5.x version, now it works as before, without problems.

I'm going to consider upgrading to version 1.6x of coppermine whith update
