Joomla 3.4.4

Having a strange issue when trying to save an article with tags. I receive the following error (which doesn't give me much info!);

article error

Whenever I remove the tags the article saves just fine.

I am creating the tags before I create the article. Using the tag manager. I have also tried to create the tag within the article which also doesn't work.

Has anybody encountered this issue in the past, is there a fix, or am I overlooking something?

Things I've tried so far;

  • delete / re-create all tags
  • purge cache / history
  • different browsers
  • error reporting (nothing obvious reported)
  • Extensions >> Manage >> Database (no issues)

Stuck with this one so any help appreciated :/

    Could you try upgrading to Joomla 3.4.4 and try again? – Lodder Sep 9 '15 at 10:45

    Not that I personally know of, however there are loads of closed issues for each release so reading through all of them would take ages. First try upgrading to 3.4.4, then if it still doesn't work, could you try adding the following to your root index.php if (extension_loaded('mbstring')) { var_dump('installed'); exit; } and let me know what the outcome is – Lodder Sep 9 '15 at 11:00
  • Hmm ok. And I assume you haven't made any changes to the core of Joomla? Do you have any plugins installed that possibly manipulate articles and how they work? – Lodder Sep 9 '15 at 12:30
  • I've just done a quick test and cannot appear to replicate the issue :/ If you go to Extensions >> Manage >> Database, are there any tables to be fixed? Long shot but could you also try taking a backup and trying on your localhost? – Lodder Sep 10 '15 at 9:29
  • Can you try enabling debug mode from the Global Config and see if there are any SQL errors? – Lodder Sep 10 '15 at 9:38

I tried various things on a clean Joomla and was not able to find anything obvious, or replicate the issue. This seems to be something specific to your site.

I can give you a few troubleshooting directions:

  1. Start disabling the majority of plugins one by one as a first step, to see if it is related with any of those.

  2. Possible originations of this message are in the following files:

    • /libraries/legacy/controller/form.php
    • /administrator/components/com_finder/controllers/filter.php
    • /administrator/components/com_menus/controllers/item.php
    • /administrator/components/com_menus/controllers/menu.php
    • /administrator/components/com_languages/controllers/override.php
    • /administrator/components/com_templates/controllers/style.php

    You will be able to locate a save function in all these files, and the point where the Save fails and returns the message you are getting, it will be the Language CONSTANT "JLIB_APPLICATION_ERROR_SAVE_FAILED".

    First see, if any kind of settings or extensions could create any kind of dependency between saving article+tags with any of the above files.

    Review the code and see if and how they might interfere with the article saving with tags. Follow the code and find all other code that is being called, and try adding your own debugging within the steps of code execution, till you find any breakpoints e.g. with die statements.

  3. Different approaches would be:

    • Re-install Joomla 3.4.4 on top of your current site.
    • Or on a clean Joomla installation, start replicating your site, by moving database tables and installing extensions in steps, so you could spot where the issue could be hidden (in a db table, an extension etc).

Remember: Whatever you do - make sure you have a backup of your site, and preferably do any kind of experiments, troubleshooting on a clone of your site (not the live one).

I would be in place to say more, if I had direct access to the site.

  • Very useful thanks @FFrewin I disabled all of the plugins so that's not the cause. I have done the same with 3rd party components (of which there are very few). I've also had at look at the files you mentioned & can see the save function in each, I'm not sure how to correctly troubleshoot with my own debugging although I will give it a try. Failing this I will as you advised, start with a fresh installation and migrate everything over one piece at a time, with continuous testing. – jonboy Sep 14 '15 at 12:04

OK I've solved this one with help from @FFrewin & @Lodder

After (painstakingly) comparing all my database tables with a similar Joomla 3.4.4 site I noticed that I was missing some rows in my #__content_types table.

I only had two rows (#__Article and #__DPCalendar), whereas I should have had around 15 rows.

I exported the populated table from a working site, and imported it to the faulty site. All is now working.

I don't know how this happened - perhaps during one of the upgrades from 3.2.x?

I will include the SQL code for future reference, run this and it will populate the #__content_types table with the correct data.
