Incrase OCMOD 64 KB limit

Compatible with OpenCart,,,,

If you would see this while you are installing an OCMOD:

Warning: DOMDocument::loadXML(): CData section not finished

Then your xml file is larger than 64 KB. In this case you can't install this mod. The solutions is simple, you have to change a database field type from text (64KB) to mediumtext (16MB). So 16MB should be enough for your OCMOD.

ALTER TABLE modification CHANGE xml xml MEDIUMTEXT CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ;

Here is a little mod, what can makes this change for you.
