Unable to upload images / JSON error

    I’ve just upgraded 1.9.3 to 2.1.2, because I was unable to edit thumbnails. After a lot of drama, I can now edit thumbnails, but am no longer able to upload any images, which is causing a huge headache.

    My first problem is that Firebug reports an error on loading the Add Gallery / Images page:

    SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

    The offending filepath is /wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_addgallery_page/static/jquery.filetree/jquery.filetree.min.js?ver=3.8.8 line 1 > eval

    Next problem is that I can’t upload anything into an existing gallery and I can’t create any new galleries. I can queue up files by clicking the ‘add files’ button etc, but as soon as I click ‘start upload’, I get the error pop-up:

    An unexpected error occured. This is most likely due to a server misconfiguration. Check your PHP error log or ask your hosting provider for assistance.

    0 images were uploaded

    I’m using WP 3.8.8, which is necessary because I depend on some plug-ins that aren’t compatible with anything more recent.

    I have disabled all other plugins and still have the problem.

    I have switched to a number of standard, clean themes (Twenty Ten etc) and that has no effect.

    Here are my server settings:

    Operating System : Linux (64 Bit)
    Server : Apache/2.2.29 (Unix) mod_ssl/2.2.29 OpenSSL/1.0.1e-fips mod_bwlimited/1.4 mod_qos/11.5

    Any idea what’s going wrong?

    I forgot to say that:

    a) This happens regardless of how many images I try and upload at the same time (1 or 3 or 10 etc), and regardless of how big they are (I’ve been testing with 180px x 180px images, all less than 100kb).

    b) This happens on both the latest versions of Firefox and Chrome.

    @simongreenland – I would suspect there could be something in the WordPress version given the description of your issue (unless there are server file permissions issues at hand).

    Have you tried mirroring the site and updating WordPress to see if this resolves the NextGEN Gallery issues you are seeing?

    Thanks for the reply, Cais.

    I did mirror the site, but the first thing I tried was rolling back NextGEN to 1.9.13. This now works – I can create new thumbnails, I can upload images, and there are no longer any JSON errors. I can’t use Flash uploader, so I’m stuck with one image at a time, but for the time being I don’t care about that, the fact is that I can upload.

    @simongreenland – Thanks for the update, although rolling back to NextGEN Legacy is not the preferred fix … I still suspect some sort of conflict so perhaps you will be able to narrow that down on the mirror site while you continue to provide a working production site.

    – Cais.
