Images not shown on mobile

Hi Jonas,

Thanks for the info!

Hmm, everything seems to be in order, so far. May I know the url of the website?

Sure, it is jotiga.de

It seems that the image resizing script (/wp-content/plugins/adaptive-images/adaptive-images/ai-main.php) is not running at all!

This is weird because it is supposed to be called from within the .htaccess file, which seems to be correctly set up.

Could you 1) run the diagnostics button from the plugin settings page and send me the output and 2) send me the contents of your .htaccess file.

(That is if there are is no sensitive information in there, of course!)

All right, hope you can catch that bug or problem ??

Everything seems alright there, too…

But wait, now that I check again I see the images in your website. I used Ctrl+F5 for a hard refresh! Did something change in the meantime?

Yes sorry, should have warned you. I deactivated the plugin in the meantime, I don’t want my clients to see a broken page. I thought you can work with the data i provided first. Do I need to reactivate it for you to further investigate this?

Well, all the debugging and diagnostics information seems OK. So I need some way to test the plugin while it is activated. But I understand that you do not want your clients to see broken images.

Could we set it up in another test environment and have it activated there perhaps some way?

Well, it is nighttime here now, so I will activate it for the next 10-12 hours. Test as much as you want ??

Here is what is happening:

Instead of serving the images at once the server is requested to filter the images from the script /wp-content/plugins/adaptive-images/adaptive-images/ai-main.php, which is inside the plugin.

This is requested by the line:

RewriteRule \.(?:jpe?g|gif|png)$ wp-content/plugins/adaptive-images/adaptive-images/ai-main.php [L]

of the .htaccess file.

But instead of running this PHP script the server returns its contents as if it were a text file! This is very strange. Could you mention this problem to your server administrator and see if it has anything to do with your server configuration?

I just did, I will get back at you when I get a response…

Thanks, I’m very curious to find out!

??

Okay problem fixed. The problem seemed to be wrong settings for my SSL certificate. I installed the plugin WordPress HTTPS and now everything works fine.

I guess the problem was that the file was loaded via http instead of https…

This is good (for the plugin) it means that there was no actual bug!

??

But it is a case I should somehow predict to help the user… Thank you for helping me debug and let me know how it works for you!
