I have read through the help and through the forum, but could not find an answer to my problem.
I would like to customize a code in a TPL that is generated by an addon. I already found out that the code is retrieved in the file vivashop / templates / blocks / product_tabs / description.tpl.
First of all I would like to recommend you to change the hook name to the one with using underscore instead of hyphen:
{hook name=“block_description:description”}
If you have already created the override for the mentioned template, then the path should the following: design/themes/[THEME_NAME]/templates/addons/[ADDON_NAME]/hooks/block_description/description.[pre|post|override].tpl
In case the override has not been made yet, create it at the following path: themes/[THEME_NAME]/templates/addons/[ADDON_NAME]/overrides/blocks/product_tabs/description.tpl/description.tpl
description.tpl in design/themes/vivashop/templates/addons/my_changes/overrides/blocks/product_tabs/
Now it worked. Thank you so much.
You have to clear the cache and apparently also set the option “Rebuild cache automatically” under admin.php?dispatch=themes.manage to “On” when testing.
Because today I saw those test data that I tried yesterday. Only with clear cache AND “Rebuild cache automatically” my data from today was visible. Very strange.
