database - WP website showing blank page after moving from subdomain to main domain

I created my website on the subfolder /.

After it was finished, I moved the website's files to the main adress / (ftp). And after that, I edited the siteurl and home record in the database in the wp_options table.

I have done this before, and as far as i rememeber, these were all the steps that were needed. However, as you can see for yourself, nothing is showing, just a blank page. Also no connection error, the page source is blank too.

What happened? What could be the cause? The only difference with other websites I moved is that I installed the Wordfence plugin. Could this be a problem? And mostly, were do i start to fix this issue?

• Can you turn on the debug log via wp-config.php? codex.wordpress/Debugging_in_WordPress#WP_DEBUG – Kumar Commented Aug 30, 2018 at 11:38
• Done, debug is now active. – Kevin Verhoeven Commented Aug 30, 2018 at 11:49
• Does the .htaccess mention the subfolder (eg in the RewriteBase line)? – kero Commented Aug 30, 2018 at 15:25
• It does, but changing it from /dev/ to / didn't change anything either. Something else i can try? – Kevin Verhoeven Commented Aug 30, 2018 at 15:39
• Log file is available in website_root/htdocs/wp-content/debug.log Can you check the file if you see anything in there? Because you seem to be getting a server 500 error. So that's probably because of your webserver or some of the code is creating a fatal error. – Kumar Commented Aug 30, 2018 at 16:27
