I found what was causing this, it was a part of my html reset css file.
There was this entry.
/* Clearing */
.clear:before,
.clear:after,
.entry-content:before,
.entry-content:after,
.comment-content:before,
.comment-content:after,
.site-header:before,
.site-header:after,
.site-content:before,
.site-content:after,
.site-footer:before,
.site-footer:after {
/* content: ''; */ <---- this line caused it
display: table;
}
I think since WPML is parsing everything to check if it should be translated, it parsed and surrounded it with a "p".
This error appeared just after switching from qtranslate to WPML.
Thanks anyway.
