Blank Page Bug

[eluser]jjpmann[/eluser]
I have just upgraded to 1.6.3 all though I have had this problem in 1.6.1. For some reason I get a blank page no errors. This does not happen all the time but has something to the with the log files. When the problem occurs I can fix by deleting the latest log file and the site works as is should.

This seems to be a on my web host server only since my test server does not do this or I haven’t seen it. I haven't come across any one with the same problem in my searches. If anyone has any ideas to help that would be great.

Thanks in advanced.

Sounds like PHP is timing out. I wonder if your disk i/o is fast enough? You can lower the level of logging you're using, or remove it entirely.

Welcome to CI jjpmann.

Ok I'll take a look at turning off the logging when the problem occurs and see if that helps. It just seems strange that its happening to the site. It's actually a beta site in a different directory (using sub-domain) then the main site with is live, running 1.5.3 I think and I have had no problems with main site. Been working on a big update and until I find a solution I wont be able to merge it over. =/

Thanks again.

I had the same problem, CI 1.6.1 works in my home, but doesnt work in my hosting. Only show me a blank page for all controllers. I would appreciate any help.

blank pages are almost always the result of a php error with error messages suppressed. Usually, its caused by not enough memory. if you run a phpinfo(), how much mem you have Carlos? Oh, and welcome to CI!

Thanks for you answer.

I don´t find where is memory, in the phpinfo(), but something worried me after read the info page, this says : "mysql Client API version: 3.23.49 ". I don't know if this is a problem because mysql must be 4.1+ version, although in my control panel said MySQL Version 4.1.22-standard.

Whatever, if the memory is the problem, how fix that?

Thanks other time.

If you search these forums, or google for "PHP increase memory" what do you find? I'll give you a hand working through the information you get back Carlos.

Hej.

I had a similar problem with a blank page with CodeIgniter.
I was searching the problem for a few weeks and than I made a pause (had no time to search the problem). Now I search again and I fixed it.

It was really a small problem, but I found the problem and fixed it.
The problem was, that I turned error logging on (later to test it, I set it to 4) but I changed the webhoster (before the problem occurs) and I forgot to set write access for all. So CI can´t write the log files. I described it in my blog:

But why breeds this a completely blank white page??

[edit]
before I fixed it I changed to the latest CI version!

Hey everyone,

Just finished a server migration and ran into these same problems. These solutions might have already been mentioned, but check the items below and see if it helps.

1. If you're using mysqli -- make sure it's installed on the machine. CI does not spit out an error, you get just a blank page no source, no nothing.

2. In your index.php file, if error reporting is set to E_ALL, make sure your logs folder is writeable. This is the error that got me

3. This happened a while ago, but running PHP in CGI mode was causing the same blank page error.

Hope that helps others out there
