I have now installed the development plugin and everything works Perfectly. Thank you.

I don’t really understand the mechanism of of mla_alt_shortcode. Who is processing the alternate parameters? Not an urgent question, the essential thing is that it works.
In any case thanks again for the help

Thank you for your reply and solution.
I have tried it without installing the development version of MLA.
The pagination links seem to work fine.
I presume the defect you mention :

an MLA defect in the way parameters are processed when [mla_gallery] is used as the alternative shortcode

is the fact that the MLA short code is dispalayed by the browser? I will soon install the development version you mention and report back.
