Have you tried disabling plugins?
I’m not seeing any significant slowdown on my network.
I have the same problem. Already deactivated all plugins, but it did not help at all. Pls help!
Solved my problem:
1) Open database via phpMyAdmin
2) Open table “wp_options” and look for “db_version” entry.
3) If that entry has a number different to “30133” (in my case ist was 29640), change it to “30133”.
4) After that, your site should fast as usual.
Hope this helped.
That worked for me too iamklaus Thanks!
Can you do me a favor? Could you please try the following:
1) Go to Network Setting
2) Updates -> Upgrade Network
Do the network upgrade and check if it is finishing. In my case I get a timeout. My database isn’t really big (less than 40 MByte), but the Upgrade does not pass successfully. I think also might be a indication to find the problem. Found already other people in the web, having the same strange problem as we do.
Also tried to debug, but didn’t find anything.
My website is within an intranet. If have proxy settings in the wp-config so that WordPress can have access to the outside world, especially to get updates.
Hmmmm… Interesting….
I thought noticed a slight slow down too… But I think it was that I need to update a chaching plugin… But in my wp_options table it just says db initiate on…
I found the table versions in my wp_blog_versions which all had been upgraded to 30133
I was going to ask if you really were running multi-site but since you asked about the network upgrade I am sure you are… Maybe your database is not set up correct (seems highly unlikely) But since we are finding values in different tables could be a starting point…
I did the network upgrade and it finished with no problems… Seems to all be correct… So maybe some weird stuff in your database… Or you intranet network is timing stuff out…
1) Go to Network Setting
2) Updates -> Upgrade Network
That SHOULD upgrade your DB. I also run a DB optomize after major upgrades, but … Well. That’s habit 🙂
Genius thanks iamklaus – had a multi site running and all 3 dashboards were super slow, the database version had to be updated in wp-options via phpmyadmin on all 3 databases
all after upgrade to 4.2
Tried using iamklaus’ suggestion for a WordPress MU upgrade to 4.3.1 but it didn’t help.
What worked for me was James Huff’s first suggestion on this thread: https://wordpress.org/support/topic/admin-back-end-slowfront-end-good?replies=11
I had to run /wp-admin/upgrade.php in the browser for each site in the network, and then my dashboard pages were fast again!
