Blank Search Page

[xtom]

I think I've found the problem at last. It's the spellchecking code in sources/search.php - If I remove the block of code below from around line 777 on this file the search works again, no more blank search page. I think it's the line pspell_new('en'); that causes it to crash to blank screen. Strangly I don't get this problem on a fresh install, only when I use it on my existing database. Anyone know why it's happening exactly? Is it safe to remove this code permanently or is there something else I can do to fix?

Before removing anything, I'd suggest seeing if disabling the spellchecker in Admin -> Forum -> Posts and Topics -> Post settings helps.

Yes disabling the spell check option works, I wasn't even aware it was enabled, thanks. Now if I only thought of this yesterday I could have saved myself a lot of time and trouble

[xenovanis]

Is aspell enabled on your server? Does the spellcheck in posts work for you?

[xtom]

My phpinfo lists PSpell Support enabled but no mention of aspell. I don't think the spell check works on posts for me either, when I click the spell check button a blank page (that's familiar) in a pop up window appears.

[xenovanis]

Sorry, I meant pspell.

Probably it's not setup correctly, or, at least not to work with SMF. You might want to try contacting your host about it.

i had this and its fixed when i changed to a better host, its a host problem
