Issues / FAQ

If for some reason you are having issues with the specified TAGS possibly here you can find an answer. If not, please do not hesitate to get in touch.

Did you follow the guide in setting up the TAGS but is the wrong title, description or image showing after sharing. Most like there is a caching issue then, either on your website or in Facebook or Twitter. Follow the steps below to purge the cache so the correct TAG is used.

Clearing cache on local website

The first check if the wrong TAG is showed on Facebook or Twitter is validate that the proper TAG is used in the source code of your website. This can be done by viewing the source code in your browser:

Step by Step Instructions using Google Chrome (similar instructions using other browsers)
  1. Open the Google Chrome web browser (if you do not have Google Chrome installed, this is a free download).
  2. Navigate to the web page you would like to examine.
  3. Right-click the page and look at the menu that appears. From that menu, click View page source.
  4. The source code for that page will now appear as a new tab in the browser.

Alternatively, you can also use the keyboard shortcuts of CTRL + U on a PC to open a window with a site's source code displayed. On a Mac, this shortcut is Command + Option + U.

Search for "TAGZ" or e.g. "og:image"

In the source code search for "TAGZ" or e.g. "og:image". Check the TAGS that are displayed here to see if they match the ones you have defined. If they match, proceed to the Facebook or Twitter part of this issue. If not clear cache of your website. Please follow this Official Joomla! link how to do so. If you are using a Content Delivery Network (or CDN) do not forget to clear cache of this as well if the TAGS are still not the right one in the source code.

Clear cache of Facebook for an url

If the source code shows the proper TAGs but sharing a page using Facebook still results in an old (or wrong) preview you most likely need to clear cache of that particular url in Facebook. For this visit the Facebook Debugger, enter the url like the image below and hit the Debug button.

Then click the Scrape again button to force a rescrape of the page:

Now the proper preview should be displayed. If not, please get in touch.

Clear cache for LinkedIn

Clearing cache for LinkedIn can be done by visiting the LinkedIn post inspector, followed by entering the particular url and hit the "inspect" button. Done!

Clear cache for Twitter Cards

Clearing cache for Twitter Cards is even more simple. In order to do so visit the Twitter Card validator, enter the url and hit "preview card". That's it! :-)

If you are having an issue which is not addressed here please get in touch.

Apparently there can be issues with Joomla uninstalling extensions. When you no longer need TAGZ and are experiencing issues uninstalling it please follow these instructions.

First try to uninstall TAGZ using the default Joomla method of uninstalling. If that doesn't work (for example with an error like Missing manifest file) try to install TAGZ again and then try to perform a new uninstall. If it still doesn't work please follow the steps below:

  1. Check (using FTP or file manager within your hosting panel) if the directory /plugins/system/tagz and/or _administrator/components/comtagz and/or _components/comtagz is existing. If any of these folders exist please remove that entire directory.
  2. Use a database manager (like phpMyAdmin) in your hosting panel to search for tagz. If present in the _extensions table remove it. You can check the steps below in the video below:

  1. Open phpMyAdmin
  2. Click the database that includes the Joomla install
  3. Click search
  4. Type tagz in the search form, select all tables and click GO
  5. If present in the _extensions table (there is a custom prefix on your install, like l6ew3_extensions) click the browse button next to the extensions table
  6. Delete the row(s) that contain tagz (note: validate that you spell tagz correctly, not tags).

If it still doesn't work or you have any questions please get in touch at
