Thanks for your question, and for taking the time to include the full source text of your [mla_gallery] shortcode. Your English is fine.
I entered your shortcode in my test system, changing the attachment_catrgory to a value that works for me. All of the other parameters are exactly as you have them.
Here is the HTML source for an item in the gallery:
<dt class="gallery-icon ">
<a href="http://mladev/wp-content/uploads/2013/08/Parse-times.pdf" target="_blank" rel="nobox"><img width="22" height="22" class="attachment-64x64" alt="Parse-times.pdf" src="http://mladev/wp-content/plugins/media-library-assistant/images/crystal/pdf.png"></a>
</dt>
As you can see, the target="_blank", rel="nobox" width="22" and ‘height=”22″` attributes are all present in the right places. As far as I can tell, MLA is working as it should.
You do not say which Lightbox plugin you are using, so I cannot tell you if there is some other reason this shortcode is not working on your system. I have used “Easy Fancybox” and “WP jQuery Lightbox“, among others with good results.
If you can tell me which plugin you are using I might be able to try it and see what happens. If your site is accessible on the internet, could you post a link to the gallery so I can see the HTML source code?
I will leave this topic unresolved for now. Please note that I am traveling from April 2 until April 13 and may not be able to respond until my return. Thanks for your patience and your interest in the plugin.
Thank you for your answer.
I use Lightbox that comes with Avada theme.
Certainly there is an incompatibility between MLA and Avada. 🙁
Item gallery’s HTML code:
<dt class='gallery-icon '>
<a rel="prettyPhoto[postimages]" href='http://www.fourti.com.br/develop/uempgb/wp-content/uploads/2015/03/UNIFAMMA.pdf'><img width="22" height="22" width="64" height="64" src="http://www.fourti.com.br/develop/uempgb/wp-content/plugins/media-library-assistant/images/crystal/pdf.png" class="attachment-64x64" alt="Edital homologação Correio" /></a>
</dt>
Thanks!
Thank you for your update. I agree, it looks like Avadais somehow modifying the links in the gallery.
Avada is a premium theme, and I cannot afford to purchase premium themes and plugins to provide MLA support. I suggest you take this issue up with the vendor. If they provide me with a copy of the theme for testing purposes I can investigate further.
For now, I am marking this topic resolved because MLA is working properly. Please update the topic if you have more information, questions or another way I can help resolve the conflict. Thanks for your interest in the plugin.
