Hi,
In this case, we would like to suggest you to take a backup of site and follow these steps:
– Update the latest version of T3v2 2.6.9.
– Backup and overwrite the templates/ja_teline_iii/html/com_content/category/ folder with my attached file.
Note: Make sure your website is still running on Joomla 3.1.5 version since there is no update of this JA Teline III template on Joomla 3.2.x at this time. Remember to clear JAT3 cache after updating changes.
If the suggestion is not effective on your website, you can send me PM with the credentials of the site. I will help you to check out it and back to give you a suitable solution then.
