(hope this is the proper forum ~)

Hi,

I have a “zombie” add-on that I cannot get rid of, and now it is interfering with my ability to edit my site (specifically, I cannot add blocks to existing pages).

Some time ago I had (presumably) installed the add-on “Load MathJax,” thinking it would come in handy should I need to display more advanced math concepts on my web pages, but I never actually used it. For quite a while I’ve been seeing notices that an update for that add-on is available, but whenever I clicked on “update,” nothing ever happened, and the notice would remain. I learned to ignore the notice.

Well, today I made the mistake of giving it another try, and of course there was no apparent change – until I tried to add a block to one of my existing web pages. I now get the following error messages, which I have never seen before:

Warning: require_once(/home2/summite4/public_html/packages/gnt_mathjax/blocks/gnt_mathjax/controller.php) [function.require-once]: failed to open stream: No such file or directory in /home2/summite4/public_html/updates/concrete5.6.2.1_updater/concrete/core/libraries/loader.php on line 218

Fatal error: require_once() [function.require]: Failed opening required '/home2/summite4/public_html/packages/gnt_mathjax/blocks/gnt_mathjax/controller.php' (include_path='/home2/summite4/public_html/libraries/3rdparty:/home2/summite4/public_html/updates/concrete5.6.2.1_updater/concrete/libraries/3rdparty:.:/usr/lib64/php:/usr/share/pear') in /home2/summite4/public_html/updates/concrete5.6.2.1_updater/concrete/core/libraries/loader.php on line 218

I can’t uninstall the add-on, because when I click on “edit,” nothing happens. If I go to the /packages directory on my server to try and get rid of it manually, there is no “gnt_mathjax” or anything even indicating that the add-on exists.

Furthermore, if I go to “System & Settings” and click on the “MathJax Settings” under “Environment,” I get the following message:

Warning: include() [function.include]: Failed opening '/home2/summite4/public_html/packages/gnt_mathjax/single_pages/dashboard/system/environment/mathjax.php' for inclusion (include_path='/home2/summite4/public_html/libraries/3rdparty:/home2/summite4/public_html/updates/concrete5.6.2.1_updater/concrete/libraries/3rdparty:.:/usr/lib64/php:/usr/share/pear') in /home2/summite4/public_html/updates/concrete5.6.2.1_updater/concrete/core/libraries/view.php on line 945

Naturally, I suspect this particular add-on is the source of all my woes, and I want to be rid of it and be able to edit my website. In particular, I just purchased a new theme and am anxious to implement a new design. In point of fact, I cannot even do that because when I try to edit new blocks arising from the change in themes, I get the errors stemming from the “require_once” function as indicated above.

I would greatly appreciate it if anyone could help me with this. I am not a coder, but I can follow direction provided they are not terribly complex or arcane :)

Thanks so much!
