Site completely down. White screen of death

You need to check the Apache error_log, this is mostly an error caused by the wrong PHP code, but could be for a lot of other reasons too, error_log is what defines where the issue is at, could be a wrong syntax, missing required file, ..etc.

Share the errors found in error log and I can help you out, you can also email me the credentials @ [email moderated] to take a quick look.

I have no idea how to do that. please advise.

what info would i be sending you?

Read this to find the error_log which you need to copy here https://my.bluehost.com/cgi/help/562#php it is for blue host and should be the same for all hosts with cpanel. Otherwise, you can email me the cpanel access to check the issue.

thanks. found this…

@tamerwin: Don’t email some random person your WordPress login info and especially not your cPanel info. That’s like mailing some random person your house keys.

@stephencottontail

Right! Thanks

@motaz_shazly, Please stop asking people to contact you.

You probably already did this, but here’s my advice anyway…

Try deactivating all of your plugins to explore whether any could be responsible. If none are, keep all plugins deactivated and switch to the Twenty Fifteen/ Fourteen theme to see whether it could an issue with your theme.

If you cannot access your dashboard, you can deactivate all of your plugins via FTP.

To deactivate all of your plugins via FTP, you just need to rename the “plugins” folder (yes the “plugins” one). Then WordPress will automatically deactivate all of your plugins. You can rename the folder name straight back afterwards.

If still that doesn’t work, you can try replacing the core WordPress files. Pay attention to the bits in bold:
Try downloading WordPress again and delete then replace your copies of everything except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings. Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.

@andrew

Did both of those already and got same result. Anything else?

The error messages that you posted would suggest that some or all of WordPress was deleted, not just your theme and plugin files.

Did you have a backup of your site before you started messing with it? You might be better off just restoring your backup and starting again from there.

In the future, you may want to make changes to your company site on a sandbox server, make sure everything works, and THEN deploy them to your live site. Right now, you won’t have a website until you resolve all of your problems.

Means that there is a missing file is the core WP files. My recommendation is to upload the core WP files found in ‘wp-admin’ and ‘wp-includes’ directories to the server, then check the error_log again if problem is not solved to see what else is wrong based on the newer messages from the error_log.

it seems like I’ve incorrectly erased and reinstalled WP. Can someone explain how to remove and restart fresh? like step by step?

The only backup that I’m aware of is the SQL database

just for clarification…

should there be a folder named WordPress in the public_html folder?

There are lots of step by step directions here: https://codex.www.ads-software.com/Installing_WordPress

But, I would try calling the hosting provider, and see if they can restore your account from a backup – that will be a lot easier than trying to reconnect WordPress files to your database.

Your site shouldn’t really be in a folder called “WordPress”, but it’s really up to you where you install WordPress. From my experience in the forums, people install wordpress in a “wordpress” folder by mistake.
