How to make WP Super Cache Work?
I am experiencing some really strange problems on my Wordpress website. So, to begin with, I have the following configuration.
Ubuntu 14.04, Apache 2.4.7 with CGI/FastCGI enabled, SSL installed and all traffic 301 to https version. Mod SPDY also enabled.
The thing is that can't make this WP super cache plugin work in preload mode. Recently, I have made a custom cron job via "crontab -e" command and added the following line:
*/1 * * * * wget -q -O - http://mywebsite.com/wp-cron.php?doing_wp_cron >/dev/null 2>&1
To be honest, I really don't know if it is a cron job problem or it's something else.
Actually, when I hit the "preload cache now" button, the plugin trigers caching activity but stucks around the 30th cached page (it's different everytime). This is done withing 20 seconds. I left it this way yesterday and now I see that for approximately 24 hours it has cached around 450 pages. Actually, I know (because I've used it in my previous hosting) that when I hit the "preload cache now" button, it caches my all 1000 pages in around 40 minutes. And the cron job for my previous account was set to
*/15 * * * * .
Does somebody have even the slight idea what may be causing this slow caching problem?
