Code appearing on settings screen

The following is appearing on the plugin setting screen – rather than category names this code is shown next to the check box… PE Category Filter Select the categories that you want to exclude from the index. Categories cat_ID, $options))? ‘checked=”checked”‘: ” ?> name=”pecf_cat-list[]” value=”cat_ID?>”/> name?> cat_ID, $options))? ‘checked=”checked”‘: ” ?> name=”pecf_cat-list[]” value=”cat_ID?>”/> name?> cat_ID, $options))? ‘checked=”checked”‘: ” ?> name=”pecf_cat-list[]” value=”cat_ID?>”/> name?> cat_ID, $options))? ‘checked=”checked”‘: ” ?> name=”pecf_cat-list[]” value=”cat_ID?>”/> name?> cat_ID, $options))? ‘checked=”checked”‘: ” ?> name=”pecf_cat-list[]” value=”cat_ID?>”/> name?> cat_ID, $options))? ‘checked=”checked”‘: ” ?> name=”pecf_cat-list[]” value=”cat_ID?>”/> name?> cat_ID, $options))? ‘checked=”checked”‘: ” ?> name=”pecf_cat-list[]” value=”cat_ID?>”/> name?> cat_ID, $options))? ‘checked=”checked”‘: ” ?> name=”pecf_cat-list[]” value=”cat_ID?>”/> name?> cat_ID, $options))? ‘checked=”checked”‘: ” ?> name=”pecf_cat-list[]” value=”cat_ID?>”/> name?> cat_ID, $options))? ‘checked=”checked”‘: ” ?> name=”pecf_cat-list[]” value=”cat_ID?>”/> name?> cat_ID, $options))? ‘checked=”checked”‘: ” ?> name=”pecf_cat-list[]” value=”cat_ID?>”/> name?> http://wordpress.org/extend/plugins/pe-category-filter/ Same here, so the filtering does not work at all (I tried checking all but one box just as a test and all categories still show on the home page). 🙁 Sad, because the other plug-in that does this has a major conflict with the theme I am using.
