White page when opening guestbook & logged-in in frontend

[bole]

I do understand German, but can't write as said before. You might understand this English, or the Dutch down here.

My guestbook still has the problem, we did not find the solution.

Dutch:
Mijn gastenboek heeft het probleem nog steeds. We hebben de fout nog niet gevonden.

Hi, I have tested in on my localhost (with preparing new version 1.4.2). I have tried to set different options and get no such problem

I have logged to your site - disabled all different settings (captcha, html purifiers, form, etc.) tested different settings and still get the blank page
I have reinstalled the guestbook on your site too, but still the same

I have checked the code if there is no return without any output but didn' find anything

EDIT

I found it, it was caused by enabled Phoca PDF plugin, so I have disabled it and now it works (it is a known issue, as there is no way to change links to PDF in Joomla!, Phoca PDF is a system plugin and it tries to search the pdf links on the site and tries to change them to phoca pdf links, but on some sites, there can be problem with the e.g. replace functions )

Ah, super!

I hadn't read your message yet, but was coming back to say that 1.4.2 solved the issue. However, you say it's something else... Is it solved with the latest phoca_pdf? I'd really like to use phoca_pdf...

[Jan]

Hi, no it is not solved in latest Phoca PDF as this is more server issue or time issue than script issue The problem is, there is no way in Joomla! 1.5 to change the links to PDF, so there must be used search and replace script and because the links are not saved in content, system plugin must be used and this can then cause problems as the whole Joomla! output needs to be searched

Hi Jan,

das Problem besteht noch immer. Hast du schon eine Lösung finden können. Das PDF Plugin habe ich übrigens garnicht. Also muss es an etwas anderem leigen. WEnn du mal nachschauen könntest wäre das nett. Ich könnte dir die Logindaten per PN schicken.

Hi, there should be new way in Joomla! 1.6 - to add specific links above article, but no experiences there for now.

For 1.5 I didn't find any other, better way to find and replace the links for now

Hi, in the error message, there is no loadaed any file from Phoca Guestbook, so you need to check all other extensions loaded and caused the problem:

1 index.php (Joomla! framework)
...
9 mod_joomlawatch_agent.php:65
10 class.joomlawatch.visit.php:224
11 jfdatabase_inherit.php:641
...
12 mysql.php:231
13 error.php:171
14 error.php:136
