Try deactivating all plugins. If that resolves the issue, reactivate each one individually until you find the cause.

If that does not resolve the issue, try switching to the Twenty Fifteen theme to rule-out a theme-specific issue (theme functions can interfere like plugins).

Thanks, James. I’ve tried all of this but nothing seems to work. Have also cleared my cache/history, just in case it was a local issue, but that hasn’t fixed my problem.

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.

I use the WordPress admin online and haven’t downloaded it on my computer. Should I download it now? I’m not particularly tech-savvy, but I’ve been able to manage basic tasks so far.

You’re not necessarily downloading it to your computer to use it. You’re downloading the files so you can use them to replace the ones on your server, essentially reinstalling them.

To work with the files on your server, you’ll need FTP or SFTP, or a file manage in your hosting account’s control panel.

It’s driving me crazy, and I’m out of my depth with the last solution that James has suggested. Ugh.

Ok, there’s a less drastic was to do it, but it could just succumb to the same problem (since you’ll be asking WordPress to reinstall WordPress).

From the Updates section of your blog’s Dashboard, click “Re-Install Now”.

Tried reinstalling, but it doesn’t seem to work. Is there anything else I can do?

If it helps, I’m on the Hemingway theme, but I don’t think that’s the problem because the issue persisted even after deactivating all plugins and switching to Twenty Fifteen.

Ok, one more that’s on the very-easy level of difficulty.

First, please make sure that your browser is up to date by visiting https://whatbrowser.org/

If it is not, please try updating your browser or switching to a different browser.

If it is, please do these two things:

1. Try clearing your browser’s cache and cookies.

2. Try with all browser extensions or add-ons temporarily disabled.

Please let us know how each step goes for you, and which browser (and version of) you’re using if you’re still having trouble.

I have tried the manual instalation method displayed here and it did not work. I have the same problem as arrrow presented. i have also tried switching to 2015, 2016 and 2014 themes and did not solve the problem. Nor the click the “Re-install Now” button. Are there any methods to fix this? Or should I start creating the site from scratch again?

Try what’s listed above.

You know what, I tried accessing my admin from another computer and that worked. That means it’s a local issue with my machine. But why? I don’t understand.

For my own laptop, this is what I did:
1. I’m on the latest version of Chrome (47).
2. I cleared all the cache and cookies.
3. Disabled all add-ons/extensions.

Nada. Still doesn’t work on my machine. Any idea why this could be happening?

Do you have any trouble with a different browser, like Firefox?

Also, are you running any sort of anti-virus or web security software?

I wonder if it’s related to this: https://www.ads-software.com/support/topic/read-this-first-wordpress-44-master-list?replies=5&view=all#post-7759534
