Thanks Scream
That had some effect - but it doesn't appear to have completely cured the problem.
Now, when clicking on a Board from the Main Page
(
http://www.forums.pctechguide.com/w3t/wwwthreads.php), the error message I get reads:
Warning: Cannot add header information - headers already sent by (output started at /virtual/w02-0016/w3t/config.inc.php:249) in /virtual/w02-0016/w3t/postlist.php on line 312
Also, something that looks as though it may be a related problem. When I try to use the Jump To box to go from one Board to another, I get the following:
Warning: Cannot add header information - headers already sent by (output started at /virtual/w02-0016/w3t/config.inc.php:249) in /virtual/w02-0016/w3t/jumper.php on line 24
