Error establishing database connection error after installing Newspaper theme

Hi,
After installing Newspaper 6 theme I encountered a problem that didn’t happen with my previous themes. There is always a database error. When people visit my site they see a note line “error establishing a database connection” they can’t see the site. I can’t use the wp-admin either because of that.

It’s when I login to my server via Putty and type some Ubuntu codes like “sudo service mysql restart” and restart my mysql database, that the problem is fixed for a brief moment, my site is working again until a new error.

Can you please help me how to fix this? Is this theme too large for the server?

Be sure to increase the base memory for your WordPress site in your wp-config.php file, to at least 64MB and preferably 96MB or more. Visual Composer and all the latest plugins like Yoast do use more memory and WP defaults to a paltry 40MB which is nothing these days.

I have mine set to 256MB but have lots of RAM.

Thanks for the reply, I did to 120 MB but the problem still continues

Good idea to look at your error log, if not done so already.

how to look at my error log?

See the support info for your hosting account — there should be an error log for your site, which helps to determine WHY something crashed, etc. — useful if you have an “attack” from a specific IP, a plugin or process crashing site, etc.

When I access the server from the DigitalOcean panel I see this, is that the error log?

Ok I found an error log

Great, now you need to look at that to see what is crashing php —

or per Lucian, send tagdiv the info at:
