There's an issue when I try to export a page.

Hi Emeric,

Maybe your Joomla has AI (sort of Resistance), mine - just listen basic php rules. Export view

please record video with problem + share link to it and tell browser name otherwise , I cannot reproduce issue.

OK, I see, thanks... I shared video with developer team already.
But name page file has also number, so for joomla is not "template", but "template12345".

And are you able from front-end editor as I did (screenshot) ?

On my website, I can export page also from Page list as you did on your video.

If somehow you cannot use any of those two export methods, you have to use PHPMyAdmin and export page manually from prefix_sppagebuilder table.

@Emeric , Becuase we couldn't reproduce issue on our side (2 different sites) our developer asked me is it possible to get access to your site.

Plus info: what browser do you used?

Thanks, we will check and let you know.

But indeed I also noticed that unusual error on your server only.

We made few tests with your website backup on our hosting and localhost - and everywhere worked OK, we were able to export pages.
As our developer said problem is on your sever settings probably "client host server filter data content type in header". Contact with hosting support or change company.
