Jade, i have a question, do i need to ALSO change every instance of the word MANUFACTURER in sideboxes manufacturer_info.php and manufacturer.php and then change the file name to
designer.php and designer_info.php?
I went into the language files and made the changes,but still have the problem of this reading

now reads BOX_HEADING_DESIGNERS was BOX_HEADING_MANUFACTURERS

and on advanced search filter results by pull down
it reads TEXT_ALL_MANUFACTURES
even tho i made the changes in the english languages files and the index files.
