Piclens not working with nextgen-gallery 1.9

Hi Alex,
First I reinstalled the media-rss.php file vers. 1.9.0, right?
Then I uploaded the nggallery.php file vers. 1.9.1 from your link, but doesn’t work.
For me, now the link opens to the PicLens’ dark wall, but no photos or thumbnails are loaded.

Please post a link

Unfortunately I’m doing these tests on a non-indexed site, because it’s a copy of the one in production. Actually I don’t even use PicLens at the moment, I’m only interested in the issue by chance, so it’s not so important to me.
However, there are errors in the back-end too, in wp-login.php file and wp-includes/pluggable.php file: Can not modify header information – headers already sent by (output started at … path to / nggallery.php: 544), and I can’t access the administration pages.
The front-side is OK, except for the PicLens visualization.
Like I said before, this question doesn’t interest me directly, it was only to make sense of it. I would say that we all can use the previous media-rss file solution, which is fine, and you can take time to fix this issue, if anyone else is interested in it.
My only question is: restore the old media-rss.php file version in the next plugin version, would give problems to someone?
Thanks

I had the same problem on many sites where I upgraded NectGen Gallery and now I uploaded the old version of media-rss.php as described above and PicLens works on all the sites.

@christian Ries

I too

It would be great you tested the bugfix, thx

Yes, test the bugfix on your sites too, because my test site isn’t well configured since I don’t use it.

I tested the file nggallery.php given by Alex: with the 2 versions of media-rss.php, I obtain a black rectangle without images nor thumbnails.

Can you post a link ?

I tryied again: now things seem to work, I have cancelled the Cache-folder, I suppose that I had a mixture of new files and old files because of the Cache.
Here is my blog to make tests:

with 1.9.1 for nggallery.php and 1.9.0 for lib/media-rss.php

So for me the problem is solved.
Thank you.
Guy

Thanks !

Works for me too in production site, not in the development one, but it’s not a plugin issue.
Thanks

Sorry, I’m here again for the same issue. Today I realized that comment field in editor page wasn’t visible, even with default theme. So, after disabling all plugins and reactivated one by one it turns out that’s Nextgen to give the “undefined error” in that field. Everything in frontend is OK, and backend works, only comment field isn’t visible.
Soon after Nextgen reactivation a message appear, I try to translate it:

The plugin has generated 1 unexpected output character during the activation. If there are “headers already sent” warning message, problems with the feed or any other problem, try disabling or removing this plugin.

So, I’ve tried to restore old nggallery.php (1.9.0) and old lib/media-rss.php (1.8.4), and everything’s fine, comments are visible in editor page.

Yesterday I successfully upgraded WordPress and Nextgen to the latest versions. I needed to do the Media-rss v1.8.4 trick to get piclens to work.

I have one further problem. I have a photo gallery page https://www.sambadoc.org.uk/gallery/?show=gallery
that shows 7 photo galleries with 5 thumbnails per gallery showing. If I, for example, click on page 2 to view the next 5 thumbnails all 7 galleries move on to page 2 and not just the gallery selected. This didn’t happen before the upgrade.
Is there a cure for this?

OK. This is a NextGen problem NOT a Piclens problem. Apologies.
