I want to point that enabling Deep scan option in Media scan mode helps to detect images added with Responsive Light-box & Gallery plugin. I didn’t use this option previously, so I slightly misjudged Media Sweep. But with it the plugin processed all media files correctly and marked truly unused media as unused with no mistakes.

Yes, REST API was disabled by plugins for security and optimization reasons.
Now https://easy-music-learning.ru/wp-json/ loads correctly.

I use 3 plugins for WordPress optimization and security and I did the following:
1. All In One Security (AIOS) – Firewall – WP REST API – Disallow unauthorized REST requests – I turned it off.
2. Clearfy – Code – Clear code – Disable JSON REST API – I turned it off.
3. Admin & Site Enhancement (ASE) – Disable Components – Disable REST API – I turned it off.

But, alas, problem still exists and I can’t scan media files. The same error is shown:
“Failed to start scan: The response is not a valid JSON response”.

And nonetheless I deleted the security header above the error “502 Bad Gateway nginx” still apperas but now not always, but when I log out from admin area or change some settings in WordPress.

By the way, other WordPress websites works on the same web server like the main website and they have the same web server settings. And the plugin works fine there without any errors. So I think the matter is somehow related not to the web-server, but to WordPress and plugins configuration.

P.S.: I think this is the best plugin that exists to clean unused media. I tried many other plugins but none of them can compare with it. As soon as I solve this problem (I hope so) I will definitely write a 5 star review on it.

I’ve turned off caching (I use ISP Manager – Website -> Optimization and DDoS protection -> Enable Cache – Disabled). But the line following line still appears below any webpage:
<!– WP Optimize page cache – https://teamupdraft.com/wp-optimize/ – page NOT cached –>

I pleased with using WP-Optimize as database tool. Yet even if cache worked fine there is no detailed options to set it up flexibly. So for caching I will figure out some other solutions such as W3 Total Cache or LiteSpeed Cache.

Thank you, Bowo! I viewed the image with Admin box disabled. Yeah, this will be perfect solution and surely will protect users from such a nasty situation. By the way, I want to say extra thanks for such a brilliant plugin! I’ve already posted 5 stars review on it. It’s totally awesome!

I asked my hosting support. They told me that mod_expires and mod_headers are activated, but the error message still appears. Wonder if there’s misunderstanding… “We successfully updated your .htaccess file”… but nginx doesn’t work with .htaccess file. May be there must be something like this “We successfully updated your nginx.conf file“.

I checked this on tastewp.com test WordPress website and it says: “Your website seems to use Cloudflare, which handles the browser caching rules”. It seems that I need to use Cloudflare for browser caching?

Additionally, on my main website if I change PHP handler from Fast CGI to CGI mode, which uses Apache server, then all works like a charm. But when I switch to Fast CGI, that uses nginx, the error from WP Optimize appears again.

Hi, @kmacharia! Thanks a lot. It works! Additional thanks for quick answer.

1. WordPress version 6.7.2.
2. PHP version 7.4.11
3.

5. Sorry, don’t know about this thing.
6. OK, probably will execute this and share results.
   
   P.S.: I installed Affiliate Links plugin on another WordPress website in the subdomain on the same server and it works nice and without this problem. There are less plugins there, but WordPress & Version are the same. I also installed the same WP theme – all works good. I think the problem is in plugins’ conflict. By comparison and exclusion method I will try to define the conflicting one.
   
   The same plugins are: Add From Server, Advanced Editor Tools, Affiliate Links, All In One WP Security, Database Backup for WordPress, Disable All WordPress Updates, Simple Page Ordering, WP-Optimize, WP Fastest Cache. So they are not the problem causing.

Thanks for answer. I will try to dig in further by myself.
Last question: does your plugin work with Mailster plugin forms?
