Browser loads a blank page when mail is read problem

[madapaka]

Hi Guys,

I've been a Roundcube fan way back 2006 and lately I'm encountering problems with regards to roundcube, when users read an email in his/her inbox, the browser loads a blank page, usually when I refresh the page it loads but nowadays, it even refreshing does not work, do any of you encountered this? How did you fix it?

TIA

I've seen a lot of these errors in roundcube's error logs:

[10-Dec-2008 09:37:36] PHP Fatal error:  Maximum execution time of 120 seconds exceeded in /var/www/html/webmail/program/lib/imap.inc on line 174

Any workaround?

TIA

I was able to fix it somehow by increasing memory_limit of php.ini and installing php-xml. It seems like RC or my php settings can't handle the load, I have six virtual domains hosted on these server.

It seems that this issue keeps on coming back, I've noticed that when all available physical RAM is used whether by an application or cache I always see this in roundcube's logs --> PHP Fatal error: Maximum execution time of 120 seconds exceeded in /var/www/html/webmail/program/lib/imap.inc on line 174 , I've scourged the forum and it seems that issue is still unresolved, has anyone able resolved this? If yes, how?

TIA

I also have experienced this issue with trying to get a second installation of roundcube to work.  

I've also attempted to increase the memory limit in php (it is currently set to 64M) but it doesn't make a difference.

I have an email server that has two domains and Postfix is configured to accept mail for either domainA or domainB. so johndoe@domainA can also be johndoe@domainB -- same email (aka johndoe can log into domainA or domainB and see the same Maildir files) just different mail servers are used for sending / receiving.

Both domainA and domainB are listed in my_destinations in postfix (i.e. they are canonical domains, not hosted)

I have installed RC for domainA already with its own independent database and user. It is functioning properly.

In a separate folder with a new installation (independent directory from domainA) I have another installation referencing a (new) seperate database and user. The installation summary ends without an issue -- everything says it is ok, I can even send a test email. The strange issue is when I attempt to do a test login (or normal login) I get a timeout error. Below are examples:

[08-Dec-2008 23:02:50] PHP Fatal error: Maximum execution time of 120 seconds exceeded in /var/www/domainB/webmail/program/lib/imap.inc on line 317
[08-Dec-2008 23:08:23] PHP Fatal error: Maximum execution time of 120 seconds exceeded in /var/www/domainB/webmail/program/lib/imap.inc on line 208

I have verified that domainB is working with IMAP as I can login to the account via thunderbird and send and receive without any problems. I have verified that all my MX and DNS records are correct -- as I can send and receive email no problem

I have tried sharing the same database as domainA but I get the same results -- a timeout and error referrencing imap.inc

Hopefully someone can help us out

I was having the same problem... Some random emails when clicked on the message list, would just load a blank page (in firefox) or just get stuck loading (in opera).

After debugging almost everything I finally noticed the "installer" directory in this last release, which performs a few tests on my server to see if it's compatible with RC and it complained about mbstring.func_overload that has to be set to 0 (zero).

So I just added "php_admin_value mbstring.func_overload 0" to RC's vhost and voila, it worked...

By the way, despite all it's said here, changing the mem_limit never helped me at all... So I thought it would be worth to share what fixed for me...

Good luck!
