Both aren't working properly when executed on viewreminders.php and viewfavorites.php
Several files are affected.
Here's my fix:

viewreminders.tmpl line 53

code:
 <input type="checkbox" name="$postrow[$i]['E$counter']" value="$Number" />
 

---

change to:

code:
 <input type="checkbox" name="E$i" value="{$postrow[$i]['Number']}" />
 

---

line 65

code:
  <input type="hidden" name="total" value="$counter" />

---

change to:

code:
 <input type="hidden" name="total" value="$topicsize" />
 

---

viewreminders.php line 62-66

code:
    $x=0;
   while ( list($postrow[$x]['Thread'],$postrow[$x]['Subject'],$postrow[$x]['Number'],$postrow[$x]['Board'],$postrow[$x]['LastPost'],$postrow[$x]['poster'],$postrow[$x]['main']) = $dbh -> fetch_array($sth)) {
      $x++;
   }
   $topicsize = $x;

change to:

code:
   $i=0;
   while ( list($postrow[$i]['Thread'],$postrow[$i]['Subject'],$postrow[$i]['Number'],$postrow[$i]['Board'],$postrow[$i]['LastPost'],$postrow[$i]['poster'],$postrow[$i]['main']) = $dbh -> fetch_array($sth)) {
      $i++;
   }
   $topicsize = $i;
