troubleshoot

  • When I have seen first time this error on Joomla 1.6 while tried to save a new article in Article Manager I was lost:

    Save Failed with the Following Error: Invalid Parent ID
  • I had been driven crazy recently by couple of my sites suddenly beginning to exhibit a very annoying behavior. Sites, which worked flawlessly over past months/years began to die when I tried to save something, from new or edited articles, modules, menu items, contacts.

    Of course the first thing I done was to look to the error logs, then to enable debug and set the error reporting level to maximum. Nothing helpful.

  • Today one of my clients asked me to find out why he is running out of available disk space, despite the fact that has an average Joomla 1.5 site with nothing extraordinary installed, and a generous 2 Gigs server space. In couple of minutes I found the first clue, the /components/libraries/cmslib/cache/ directory has a whopping 700 Megs plus worth of content consisting by outdated cache files. From there finding the culprit was easy - it's the Jom Comment component which is filling up the server space with unneeded cache files. The fix was promised sometime back in 2009, but seemingly was never implemented - at least not in the Joomla 1.5 versions.

    What you can do?

  • After upgrade to Joomla 3.2 from previous Joomla 3.* versions you might see the above error message in the backend, or, worse, you simply don't receive any e-mail notifications you usually do. And the site worked just fine before the upgrade!!

    If you have registration enabled, or you use the site to interact with your visitors/customers the side effects can be really damaging - nobody gets any mails - and you evend don't see any notice about, until you began to dig for the causes, and, for example, try to send a message for yourself from backend. This potentially can roun your online business or community. Apparently everything is OK, all settings are correct, but the mails are simply not sent.

    What's the cause and, more important, how you can fix it?

  • Mastering the Web is a never ending learning process. You can learn from both good and bad examples. Unfortunately most of us are learning from their own mistakes. A well known situation is that you got a brand new Joomla site, latest tricks, stunning design, appealing content, but you miss a key ingredient of the success: the Visitor. And you've wondering, why they aren't coming, despite your SEO efforts as sending out marketing e-mails to your closest 10.000 "friends" and spending nice money in buying incoming links and lots of postings on every imaginable social marketing site, blog and forum. It's not obvious, but the problem may be in what you did, and not in what you missed. Anyway, here's a mix of things usually Joomla webmasters are doing wrong. Learn from, and try to avoid these most common mistakes!

  • You may already seen this annoying message instead of your Joomla site:

    This site is temporarily unavailable.
    Please notify the System Administrator.

    And you are virtually clueless what to do about, and even the smallest bit of info on what happened can be a lifesaver.

  • The WYSIWYG editors are great additions to the Joomla, and we have lots of them around. They make a webmaster from casual user and can speed up the work of pros. But, sometimes, you find that you cannot enter text into the HTML editor, or click on the HTML editor's toolbar buttons - you are locked out of editing your content!

    What can be more annoying as being unable to edit your own site?

  • Joomla generally is running at an acceptable speed -  users aren't seeing differences between an average Joomla site and another CMS'es. But what if they do? What can cause the (sometime unbearable) slowness of some Joomla sites?

  • After moving a site to a new server I found this error in the backend - at least one error per page, but casually even more.

    XML Parsing Error at. Error

    No error number, no line number... What a heck!

  • Sometimes when you publish a new menu item, and everything seems to be OK, when you try to access the new menu item you just created you hit the wall: instead of the intended content you'll see the following error:

    You are not authorized to view this resource.
    You need to login.

    Even more confusing can be the situation when a link which used to work behaves this way. The target content item is published, access rights are set to Public, and you still got this message! What can be wrong here?

  • You just upgraded your Joomla site to latest Joomla 2.5 or 3.* and your regular, registered users cannot login to the frontend, seeing this error:

    "You cannot access the private section of this site"

  • It's annoying... your own Joomla site don't let you log in in the backend, and you see the above error message... What's happened?

    Humm, there are couple of things you can do. Contrary of the lots of "smart" blog entries on the subject out there (last search revealed about 2 million hits) in most of the cases, regardless to Joomla version the cause is simple:
