How to clear WordPress Cache from Server/FTP/Remote location

by

I don’t normally work in wordpress, having hard time finding a lot of things.

I added one line of custom php to a template file in child theme, and i forgot a semi colon. Now the site will not load and is stuck loading forever. Most of the time when this happens to me in Drupal, i simply re-save the file and refresh; wordpress doesn’t work like this apparently..

Where is the default WordPress caching saved and which file(s) do I remove/edit to force WP to clear it’s caches? I cannot access the website whatsoever, it wont load. The only access i have is FTP. If I cannot just delete the cache, what options do I have in the current situation im in?

WordPress has no native page source output caching. In vanilla installation changes to templates should show up immediately.

If that doesn’t happen there are several possible reasons:

  • there is static page cache plugin installed, which serves stale version (the specific implementation of cache would depend on a plugin);
  • there is a caching layer between the site and internet, such as reverse proxy provided by hosting;
  • site has HTTP headers configured in a way that causes browser (or possibly proxy server in route) to cache overly aggressively;
  • PHP has opcode cache installed (which is good/normal) and is configured to cache it aggressively/longer (uncommon), which might cause it to ignore PHP source changes in file for a while.
