We need more information. What is your DPL query? Can you enable the full error messages and give the full stack trace?

This is my query

<DPL>
 resultsheader= === A ===
 namespace = Terms
 shownamespace = false
 titlematch = A%
 </DPL>

I did this for each letter through the alphabet. The Terms namespace is set to 100. I'm not sure how to enable the full error messages or give a full stack trace, but I will try to figure it out. Thank you.

I cannot figure out how to turn on the full error message. --24.250.201.191 14:37, 1 October 2007 (CEST)

1. You should put a '\n' behind the resultsheader, otherwise you will not get a heading.
2. Does the error depend on the namespace?
3. Does it work for one single letter? How do you do the "loop" for each letter? (If here is another extension involved, that could be the reason, too)
4. For full error information you must set $wgShowExceptionDetails = true; in the LocalSettings.php

1. I'm not sure where to put the '\n' behind the resultsheader? At the very end, or just at the end of the word header, instead of an = ?
2. I've removed the namespace and shownamespace from the query, so it just looks for titlematch = A%
3. I am testing it on a page for a single letter only, A . It used to be set for each letter, just repeating the query for each.
4. I set the full error information, after turning off all other installed extensions, and only received the error,

Parse error: parse error, unexpected T_REQUIRE_ONCE in /home/wikistoc/public_html/wiki/LocalSettings.php on line 161

I should add, line 161 is where the require call to DynamicPageList.php is.

I have tried a streamlined query and still the same error,

<DPL>
  titlematch = A%
 </DPL>

So we are coming closer.

1. the '\n' should be at the very end of the line where you define your resultsheader. Otherwise the first line of your output will not start in a new line and the wiki parser will not recognize the "== ... ==" pattern as a chapter headline.
2. I suspect that you have a syntax error in your LocalSettings (maybe you forgot a semicolon or a bracket in some line above 161.
3. The fact that the most primitive DPL query ("titlematch=A%") leads to an error indicates that there must be a more fundamental problem with your wiki (outside DPL).

You should:

1. comment out the requireOnce for DPL and check if your wiki runs stably.
2. make sure that you have the latest DPL revision. You only need the three files in subdirectory DynamicPageList.
3. uncomment the DPL requireOnce and check that pages which do NOT use DPL behave normal.
4. try a DPL statement with a wrong parameter, eg. "dummy=nonsense". You should get an error message from DPL. The trick with this that you only touch 3% of the whole DPL source code if there is an error in the parameters.
5. then you can try your query again and see what happens.

Then you should leave a message here again. (Is your wiki online available?)
