There is an error in the code. If the word limit is active, the rest of the parsing options are ignored.
To fix it:
Edit the file
mod_jw_srfr.php, lines 208 and 209
You will see this:
// Word limitation
if ($srfr_fi_words) {
$introtext = word_limiter($item->get_description(),$srfr_fi_words);
$fulltext = word_limiter($item->get_content(),$srfr_fi_words);
}
Change it for this:
// Word limitation
if ($srfr_fi_words) {
$introtext = word_limiter($introtext,$srfr_fi_words);
$fulltext = word_limiter($fulltext,$srfr_fi_words);
}
It fixes the problem. If you take a look the lines 189-210 you'll understand the changes.
Cheers!
