Description of my issue:
Hello. I started testing CComment Pro 5.3.
1) On transifex.com there are no such files as: "en-GB.lib_compojoom.ini", "en-GB.lib_compojoom.sys.ini" in "libraries/compojoom/language/en-GB". Because of this, there is no translation for the lines (Figure 1, 2).
2) Tested on a "clean" version of Joomla 2.5.28 and 3.3.6. Just install the sample data. In 2.5 and 3.3 there is an error. Figure 3: "Warning: array_intersect(): Argument #2 is not an array in D:\Joomla\test-lokalizatsij\domains\test-lokalizatsij-j3\components\com_comment\helpers\security.php on line 277".
