[SOLVED] Warning: domdocument() expects at least 1 parameter, 0 given

Hi,

Thanks for reading.

I have been using an rss-feed reader script for quite a while now,

but all of a sudden, it started crapping out on Me...

I made NO changes to this script and have not even changed anything

to the code that accesses this script, so I have no clue as to why

this is happening.

Any ideas as to why this is happening all of a sudden

and how to fix it?

I'll include the code below.

Thank you VERY MUCH for your help!

Thanks,

FirstBorn

Here is the Error:

Hi Mchl,

Thank you for your reply.

k, I'll go through the comments on that page,

but why is the script all of a sudden just

crapping out and not working after it HAS been

working for over a month?

Any ideas?

Thanks,

Probably your hosting company has enabled another extension, that is conflicting with DOMDocument (that's what comments in manual suggest)

Hi Mchl,

Thanks for explaining.

k, I have My php.ini file from the webhost and the .dll file

is commented out... Of course, 'cause it's on a linux server.

So, I've looked through the document that you provided

and can't find anything else that might be conflicting.

But, then again, I'm no php.ini "expert"  :-\

Any Ideas?

Thanks,

use phpinfo() if indeed both these extensions are loaded. Then consult your hosting company on how to disable one if needed.

Hi Mchl,

Thanks for your help.

I actually did a phpinfo(); and noticed that 4.xx was running

for some reason... I went into the CPanel into the php configuration,

and changed it BACK to 5 and that fixed the issue...

I have no clue as to why it swapped backwards to 4 and the

webhost said that nobody has touched the server in 14 days...

Weird, VERY Weird, but it's currently fixed...

Again, thank you VERY much for your help!

Thanks,

FirstBorn

You're welcome. Glad I could help.
