Is this issue now fixed? I’ve just applied the fix provided by @quangthien27 thank you and that worked – but I’m now reading that others are experiencing blowback from deprecation and other things?
Is this issue to do with a premium plugin vs free? or just a version update problem?
thanks

Are the user’s meta options editable in the code somewhere James do you know?

Well done that man!

Thanks James ??

Thank James!!!!!!

You saved my sorry bacon. Glad you’re resourceful as NO-ONE came to help out – I did exactly the same as you ?? 500 products and now met with a blank screen.
I shall do as you say immediately…

Hi Travellers. I looked for this file but I think woo commerce have changed since you created this post and I can’t find it. Can’t even find a folder called classes?

Are you familiar with the new version of woo commerce (woocommerce3) and would you be able to help me out as I am having the same problem you had.

Thanks

Yes, there is a fix gruber.

open your wp-config.php file and add the following line at the very top after the php opening tag.

define('CONCATENATE_SCRIPTS', false);

That should fix the problem. Let me know what happens

@teresajean. Hi this IS a different issue. Your issue is solved by doing the following:

open your wp-config file

copy the following piece of code:
define('CONCATENATE_SCRIPTS', false );

place the copied piece of code just before the [[ require_once(ABSPATH . 'wp-settings.php'); ]] line:

This should solve your problem.

rlawrentz if you are still following this thread, can you provide steps that might help other folk on here? I notice your settings were applied in your firewall.

Hi Gabriel. Thanks for the suggestion. Yes, it was the first thing I tried.
We’ve discovered that it is to do with some anti virus software on certain machines.

Great news rlawrentz! ?? Glad you’re sorted.

@kirayamato1992. Sorry! I missed your last post. Your anti virus software will have settings or preferences. Within those settings there will be a tab which has

Hide information about my computer and web browser

and

Hide information about the last web site visited

In VirusBarrier this is found under the ‘Surf’ tab.
If you have AVG or another you will have to hunt for the options. They may be slightly worded differently. If you find them can you post them on this thread please?

Best of luck!

Hi Clara_readinga.

We’ll do this a step at a time.

First question, what computer are you running, mac or pc?

The first thing to check is your user-agent.

Go to the following website https://whatsmyuseragent.com. Upon entry the first blue box you see will show you what your user agent is, mine used to say exactly this:

Your User Agent: Mozilla/5.0 (000000000; 00000 000 00 0 000000) DDDDDDDDDDDDDDDDDD DDDDDDD DDDD DDDDDD DDDDDDDDDDD DDDDDDDDDDDDD

Copy and paste your user agent in a reply to this post if it looks similar to my old one above.

If, however, it looks something like this:

Mozilla/5.0 (iPad/Mac/Windows NT 6.1 whatever; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.102011-10-16 20:23:50

Then don’t show it on the reply but please let me know it looks similar.

IT IS SOLVED!!!! This is what the problem was.
My anti-virus had an anonymiser running which was hiding details of my operating system and web browser detail. Specially it was obfuscating my web browsers user agent strings: which looked like this: Mozilla/5.0 (000000000; 00000 000 00 0 0000; 0000000) DDDDDDDDDDDDDD DDDDDDDDDDDDDD

WordPress was not able to determine whether any of my browsers were up to date and therefore had hidden the buttons from the admin screen. Upon disabling this annoymiser, full functionality has been restored in my wordpress admin.

My virus software is VirusBarrier, but presumably this may apply to any software that has a “Hide information about my computer and web browser” checkbox.

I hope this helps somebody else.

Having done some more extensive research – I believe the problem lies with the version of system software running on the laptops.
For example the mac laptop is using 10.6.8 and no browser shows the Visual/HTML buttons in WordPress 3.4.1. However, they are there for all WP 3.3.x iterations.
While Safari cannot be upgraded past 5.7.x on Mac OS 10.6.8 Firefox can be upgraded to the latest browser. This shows that it can’t be the version of browser which is causing the problem but must be a system issue.

OK. I’ve discovered that this is only happening to me on laptops. How many of you are using laptops to update your sites?
On a desktop machine the Visual/HTML buttons load. However, on a laptop not only are the buttons missing but the code is as well!
Around line 240 in the source code should be the aTags for both buttons.
However, on my laptop this code is missing!.
I tried it on another 3 laptops (two were PCs, my other two are macs) – all with exactly the same issue. All the usual tests have been tried out including the suggestions here but even two computers (one a laptop/one a desktop) running on the same network both using ethernet or WiFi (tested both) respond with the desktop machine serving the buttons and the laptop not.
Any ideas?
