slideshow stopped working on plugin upgrade

Meteor Slides doesn’t edit or change the images in any way, this is all handled by WordPress itself. When the slide images are uploaded, WordPress will crop them to fit the slideshow if they are too large. If the slide images match the size of the slideshow dimensions they won’t be edited.

But here are only two ways I can see your images becoming corrupted. Either they weren’t formatted correctly to begin with, like being in CMYK color format or something, you can save the images for the Web in Photoshop to make sure they are formatted correctly. Or the other issue could be a plugin conflict, like if you had another plugin active that adds watermarks to images.

Try checking your other plugins and the original slide images and re-uploading the slide images after you have confirmed that they are alright.

The images were created in photoshop, as rgbs, and saved for web as png 8bit. I switched the images with images that no longer have a transparent background, but the background color of the footer. At least now the slide is showing correctly, though you can see in the code, that the images have been renamed again.

Also, the images continue being shown in a vertically stretched way in the backend, when I look at the slides:

So something is still terribly wrong….

Any ideas?

It really looks like something is not quite right with those image files, could you send me one of the original slide images before it has been updated to WordPress? If you could also send the original TIF or PSD or whatever that would be helpful too.

Vanesa, I took a look and I found the source of the problem. There was a conflict with your theme, this is pretty common with ThemeForest themes.

The theme was loading a plugin that was bundled with the theme called “Custom Image Sizes”. This was breaking the way WordPress sizes images.

I commented out the line in your functions.php file that was adding this plugin:

//include_once($temp_root . 'include/plugin/filosofo-image/filosofo-custom-image-sizes.php'); // Custom image size plugin

The thumbnails for the slides in the admin are now rendering correctly, and I’m guessing you won’t have anymore problems with the slides on the frontend either. But I would recommend using PNG-24 when you are saving transparent images for the web, they will generally be higher quality. PNG-8 is indexed and is really no different than using a GIF, so the edges can get rough when you have any feathering or fine detail on your text, indexed transparency only looks good with very simple, crisp shapes.

I really don’t know what your theme was using the Custom Image Sizes plugin for, probably just to size thumbnails in the theme the wrong way. You might have some minor issues from not having it, but if your images are sized correctly to begin with, the theme won’t have to fall back on this workaround it was using.

Thank you!

I will notify the thememakers about this conflict.

I actually had to delete the old transparent pngs, as they seemed “permanently damaged”. After uploading them again the slideshow works perfectly! Thank you!

Is there a way to comment out that line out through Code snippets (https://code-snippets.bungeshea.com/)? That way the change wouldn’t get lost if I update the theme.

Thank you!!!

Cheers,
Vanesa

You’re welcome Vanesa! That include isn’t inside a function, so there’s no way to disable it via a hook.

But it might be possible to disable the function or functions inside the included file instead. I’m not sure I can’t access that file from the admin, if you want to send me a copy of filosofo-custom-image-sizes.php from your theme I can take a look.

Not sure if this is the right place but we have been using Meteor Slides on our modified (by Josh) front page in News Magazine Theme 640. Worked terrific but a couple of days ago put up a new slide and bam NO slides showing at all. nor in other slide shows. Tried deactivating/Activating, upgrading (v1.5)reinstalling the header.php all to no avail.
Our site is https://www.martley.org.uk There should be banner slides 728*90 to the left of the radio station advert.
Thanks Rich.

Hi Rich, this isn’t related to the original post in this thread.

The slideshow is loading fine, but it isn’t working because there are some JavaScript issues. The cycle and jQuery scripts that power the slideshow are being disabled and reloaded from a third party which is breaking it.

You probably have a plugin conflict, try deactivating your other plugins and testing the slideshow to see which one is conflicting.

Hi Josh, Thanks (again)
FYI I switched off plugins (how they accumulate!) alphabetically -guess what, it was WordPress Gallery v1.4 by Jealous Designs that caused the conflict

Good to hear you found the source of the problem!
