Wordpress takes too much time (100 seconds) to load - Front end and back end

Question

I am facing a strange issue of WordPress taking 100+ seconds to load in backend as well as front end. My website is nawkaar9.com hosted on Digital Ocean 512 MB Ubuntu VM. I read a tons of answers and I have tried the following solutions:

1. Disable Plugins - I disabled all of them at once and still the issue persists .
2. Switch to default theme - I switched to twenty thirteen but no results.
3. P3 Profiler plugin - Actually there was no point in installing this plugin as the issue persisted even after disabling ALL plugins but still I installed this plugin and checked the stats. I enabled a few basic plugins from site to get some stats. Check the attached screenshot. Strange thing is it shows everything as normal. 0.3 sec as load time

4. Used Query Monitor - It shows 100 + seconds it takes to load. Shows some warnings and notice but no errors as such.

5. Updated WordPress from 4.6 to 4.8 - Still Issue persists

6. Rebooted Droplet - same here
7. Restarted Services - Apache & MySQL

8. Doubled RAM limit for WP in wp-config from 128 to 256

   10. Checked HardDisk space - 50% is free
   11. Swap of 1GB already exists and most of it is free
   12. Asked Digital Ocean support - they say everything is fine from there side, the issue is with plugin or theme
   13. Set wp-debug to true but there are no errors
   14. Created New HtAccess file through permalinks settings

   Some say upgrade your VM to 1GB plan. But honestly it was working fine till date as traffic on website is low and also used free -m to be sure.

Please let me know if I am still missing anything or suggest something that I can try out.

Thanks in Advance

Answer 1

You should not ignore those warnings. From screenshot, It shows your theme is using deprecated mysql functions. Check your apache2 logs -> If this is really an issue there will ton of logging If yes, your theme is causing the issue.

If the above is true, do this:

1) Switch to some other theme.

2) Remove the parent theme code. (instead of just disabling it)

3)Upload the latest version of theme.(I am Assuming the update for that theme is available)

Let me know if that works.

If you're not already doing so, you can run a plugin like WP Super Cache which will create static HTML pages of most things to serve them up to users. I recommend this one specifically because it is maintained by Automattic.

Another plugin you can use is one like WP-Optimize which will clean up things in your database like removing auto-draft/trashed posts, etc.

Other than that, you're probably going to have to contact your hosting provider's support team and take this up with them.

Check your PHP Memory Limit and your PHP Post Max Size on your php.ini, also update your php version to 7 onwards.
