Hi again,
I checked again truckepedia.co.uk via file manager in your control panel (it’s the same site I checked before) and the geodirectory folder is indeed missing inside the wp-content/languages folder and the translation file for GeoDirectory is not there either.
For sure you have skipped point 4 of the tutorial. I can’t tell what else hasn’t be done because I don’t see the translation file anywhere.
Please follow the 6 steps that can be found below the video (it’s the same 6 points that I pasted in my previous reply). https://wpgeodirectory.com/docs/translate-core/
I went through that procedure countless times and if followed by the book, it works 100% of times. Unfortunately it is really not possible to make it simpler.
Let us know how you went,
Thanks
