Blank-outs in back-end interface

Permalink
Hi C5,

I have been having this annoyance crop up repeatedly of late and can't seem to trace it back to when it started. Occasionally when I click to open the dashboard, I end up with a blank side bar with an "ACCESS DENIED" message. (Yes I am logged in and yes I am the adminatrator with all admin's rights). I have tried to sign out - sign in repeatedly - same thing. Clear cache (even though it's off) - same thing. I can add pages, edit pages. To get to my dashboard, I have to navigate to it (eg www. mysite.com/dashboard) and it opens. The problem sems to go away after I sign off for several hours.
More annoyingly, occaionally when I clieck on the gear icon, and choose 'Design', the page slides in but ... it's blank. I can choose attributes, versions, anything else on the gear menu and it shows up and works.
Most annoyingly,occasionally when adding a block and I choose 'Stacks' from the drop down, the menu comes up but ... you guese it—it's blank. Thankfully none of these blank -outs occur at the same time.
Any ideas?
I have switched providers recently (switched from Arvixe with 30 minute load times—all of which was due to my site and not their server that was down 5 times in 3 weeks—to A2 hosting - they ROCK!Lload times are as close to intantaneous as any human can measure) but the blank outs started well after the switch and well after upgrading to 5.7.5.1.
I don't want to have to install a backup copy because my site is still being constructed - into the translation phase of the Enlgish site and I would hate to lose all those hours of work but I am not even close to having the knowledge of where to look or even notice what is wrong in the code if I was standing in it.
Any insight would be greatly appreciated.

Hi MarcYBB,

"To get to my dashboard, I have to navigate to it (eg www. mysite.com/dashboard) and it opens. The problem sems to go away after I sign off for several hours."

Are you using any type of caching through your web host?

Is there any pattern to the blank menus? Do they happen before or after a certain event or action?

When did the blank menu problem start? Were there any changes, additions, events, or actions before the start time?

Hi MrKDilkington
Thanks for getting back so quickly and sorry for not following up...
The problem is still present and I am sure it has to do with caching. Caching is turned off for my site within C5 dashboard. I modified my htaccess file and removed all of the following code after reading up on server settings:

<IfModule mod_expires.c>
# Enable expirations
ExpiresActive On
# Default directive
ExpiresDefault "access plus 1 month"
# My favicon
ExpiresByType image/x-icon "access plus 1 year▒
# Images
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"
ExpiresByType image/txt  "access plus 1 month"
ExpiresByType image/html  "access plus 1 month"
# CSS


Then I noticed the htacess file still contains this code:

FileETag None
# Turn on Expires and set default to 1 year
ExpiresActive On
ExpiresDefault A29030400
IndexIgnore *
# disable directory browsing
Options All -Indexes


I am afraid to break access to my site by playing around further. Any insights?

Another couple of issues have cropped up -
The first one is changes I have made to the theme via customization (when the design widget opened) have only been applied to the EN_ca languarge portion of my site, leaving all the pages below FR_ca unchanged...
The second is image sliders that are active on a page show up as blank when I go to edit them (add-on is Whale Owl Carousel). I can copy one to the clip board, paste it elsewhere and see that it is displaying but showing up blank (meaning the carousel shows up as having no slides when in editing mode).

Again my programming knowledge is next to nil so I don't know where to start...
