When working with custom language files in Joomla, users often encounter various errors that can cause the localization of the website to malfunction. These errors can have different causes, and their resolution requires a detailed understanding of how language files work in Joomla. This article will focus on the most common localization errors and offer solutions to prevent them.

Incorrect File Encoding

One of the most common errors is incorrect file encoding. Language files in Joomla must be in UTF-8 format without BOM (Byte Order Mark). If a file contains BOM or is in a different encoding, there may be problems with reading the file and subsequently errors in localization. The solution is to use a text editor that allows saving files in the correct format.

Missing or Incorrect Key Strings

Another common issue is missing or incorrectly defined key strings. Each language file contains strings used on the website. If a key string is missing or incorrectly entered, the corresponding text will not display correctly on the website. It is important to carefully check whether all necessary strings are present and correctly defined.

Conflicts Between Language Files

If you use multiple custom language files or combine custom files with pre-installed ones, conflicts may arise. These conflicts typically manifest as incorrect texts displayed on the website. To avoid conflicts, it is recommended to carefully organize language files and ensure that key strings do not overlap.

Incorrect File Paths

For proper functioning, language files must be placed in the correct folders. If a file is placed in the wrong folder, Joomla will not be able to load it correctly. Make sure that files for the administrator interface are in the administrator/language/[language_code]/ folder and files for the front-end are in the language/[language_code]/ folder.

Proper localization is crucial for achieving a good user experience on any multilingual website. When creating and editing custom language files in Joomla, it is important to avoid the aforementioned errors. With careful preparation, correct settings, and organization, most localization issues can be effectively addressed.
