Answered White screen after logging into the manager.

Hi!
I'm testing out Revo for our site and I've started getting a blank white screen after I log in to the manager. It installed successfully and I've logged in and done a decent amount of work with it. I tend to leave it logged in so I've only gone through the log in process once or twice. I tried to log in from a different computer today and I got a 500 error after entering my credentials and submitting. I turned on error reporting in .htaccess and it gave me a blank white screen. I got on another computer where I was already logged in to the manger and I was still logged in and able to interact with the manager normally. I logged out and tried to log back in and got the blank white screen there too. I cleared everything from core/cache/ and tried again but got the same result. I'm not sure what else to try. Any suggestions?

Thanks!

Disable .htaccess (rename) entirely, see if that helps. If it does, then debug .htaccess. Does the front end work?

Also try disabling compress_css and compress_js in system settings. If you can't get to the system settings via the manager, you can set both to 0 in the system_settings table.

Okay, I disabled .htaccess in httpd.conf and restarted the server but it still gives me the 500 error on log in. Then I changed the compress_css and compress_js settings to 0 in the database but still no dice.

Did you clear the cache folder?

I did. I checked the permissions on config.inc.php as well and they're set to 644. Is this correct?

Did you clear your browser cache and cookies? A leftover cookie can cause all kinds of weirdness.

I did but it didn't help. I first discovered the problem when logging in from a computer that I had never tried to log in from before so I didn't expect it to but it never hurts.

Hey! It's working again!

I had run setup in upgrade mode and cleared the cache previously with no luck but I had not tried steps 2,3 and 4 that you mentioned. Unfortunately I did all three of them at once and then cleared the cache directory again instead of clearing and checking after each step like I should have so I don't know which step did the trick but one of them definitely did it!

Thanks a ton!

Edit:
I've gone through one-by-one and re-enabled everything, logging out and back in after each step, and everything seems to be fine now. My guess is that I changed something things, very likely in the FURL area and/or htaccess, and then continued to use the manager without logging out. I think I may have even restarted the server once and found, after restart, that my session in the manger was still active so I just continued to use it. Some combination of these things must have screwed something up somewhere that clearing the cache by itself didn't fix. [ed. note: dwillis210 last edited this post 11 years, 8 months ago.]
