    I was on 3.5.2 and did upgrade to 3.6 when I got the following message:
    Fatal error: Call to a member function add_menu() on a non-object in /home/content/47/10522347/html/wp-content/plugins/wp-native-dashboard/langswitcher.php on line 28

    After removing the plugin, I was able to complete the update and access the dashboard.

    Now, the primary site for the multisite installation is working as it should. However, the secondary site has a 404 error when I try to access the homepage. Accessing any other page does not give this error and the page loads as it should. I can login to the dashboard for this secondary site as well. Basically, all the functionality of both site is working with the exception of the homepage for the secondary site. For example, all these pages would load correctly:
    https://www.mysite.com/
    https://www.mysite.com/contact/
    https://www.mysite.com/wp-admin/
    https://www.mysite.com/es/wp-admin/
    https://www.mysite.com/es/contact/
    https://www.mysite.com/wp-admin/network/
    The only page that would not load correctly is:
    https://www.mysite.com/es/

    Also, I typically have a static homepage and blog posts are published on a Blog page. When I chane this and try to access the static page directly it loads. For example:
    typically the secondary site would be https://www.mysite.com/es/
    this would typically load the Home page
    after changing the dashboard setting to use the lates blog posts as the home page, I can go to https://www.mysite.com/es/home and the page loads

    I checked .htaccess and it has not changed since I setup WP Multisite in May of last year.

    Any idea what could cause that?

    I believe the problems with JustHost.com have been resolved. If you’re still having problems then you may want to start by contacting JustHost to confirm everything should be working. After that, you may want to start a new support topic to see if anyone can help.

    @sohanjain
    Your issue seems significantly different from my own. You should probably start a new support topic to see if anyone can help you figure out the problem.

    @triciabu
    The fatal error you’re getting was part of my original problem. You see the address the error provides:

    /web/wp-content/plugins/wp-native-dashboard/langswitcher.php

    This says the problem is in your plugins folder, and within a plugin called wp-native-dashboard. Specifically, the problem is in the langswitcher.php file on line 28. However, all you need to know is that wp-native-dashboard is not working.

    You can remove this plugin by moving it to a different folder on your server or deleting it entirely. This can be done through FTP or using the file manager in your hosting dashboard/cpanel.

    If you need further assistance with this you may want to setup a new support topic. I simply removed the plugin from my WP installation and stopped using it. If you need to use that plugin then you will need someone more knowledgeable than myself. A new support topic could help you find other solutions.

    Thank you, I did end up going through FTP & change that plugin to “old” and that let me back in & do the update again with success. That plugin still doesn’t work so left deactivated.

    It worked now.. ??
    I just tried several methods to resolve the problem but I failed,,
    I contacted my justhost support team, and they just did somthing, then they asked me to empty my browser cash, voila ..
    My problem has been vanished.. ??

    I had a problem after messing around and moving site between domains to here: https://www.xn--ledlysprer-j6a.no/. I got the error: Fatal error: Call to undefined function wp_unslash(). What I suspect was that the wp-includes folder was from version 3.5.2 and the wp-admin folder was from 3.6. SO I just deleted wp-admin and uploaded wp-admin from version 3.5.2. Then it worked again and the error message was gone.

    I get the exact same error msg when trying to access the Admin Panel, otherwise the site works

    Error message: Fatal error: Call to a member function add_menu() on a non-object in /home/content/46/11441146/html/wp-content/plugins/wp-native-dashboard/langswitcher.php on line 28
    -GoDaddy
    -Apache/Unix
    Yesterday:
    -I had not updated from 3.5.2 to 3.6
    -Several plug-ins indicated need for update, I chose update all
    Today about 5:30AM (7/4/13):
    -The RSS feed plug-in (wp-rss-multi-importer) indicated need for update, I thought it had been updated the day before. I chose to update the RSS feed and immediately got the Fatal error and lost access to the Admin Panel
    -Tried to access through GoDaddy’s admin, got same result.
    -GoDaddy allowed for upgrade to 3.6 w/out going to Admin Panel. I updated to 3.6 hoping that might solve problem. Update was successful.
    – The site still works but I still cannot access the admin panel

    Because of the sequence of events it seems likely that the error might be caused by the RSS feed plugin update.

    I’m a bit out of my element and would appreciate any help.

    With the advice of GoDaddy and the developer of wp-rss-multi-importer I have removed the wp-native-dashboard folder. As a result;
    1) I was able to access the admin panel
    2) wp-rss-multi-importer was still in need of update
    3) The RSS feed updated without error
    4) All again is right with the world

    I will reassess my need for wp-native-dashboard.

    Follow-up:
    https://www.ads-software.com/support/plugin/wp-native-dashboard

    The problem does appear to be with wp-native-dashboard. I assume a fix is coming, the latest post seems to address the issue. However, I will wait.

    Update this AM (8/5/13) from 3.5.2 to 3.6 for multisite.

    It upgraded fine and I updated network and it said all done.

    The second site came up as a blank page. No error, no nothing. Just a white page. The site dashboard for the second addon site also came up as a blank white page.

    I reloaded the server backup from hosting site and have 3.5.2 running again. i will not upgrade to 3.6 until I see that this is fixed.

    I had change from single site WP to multisite WP about a year ago by modifying code for htaccess call and a few other things to manage domain names on sevrver side that were needed to get multisite to work. It has been fine. I upgraded to WP 3.5.2 fom 3.5.1 with no issues. I hope 3.6 is not wiping out the code I put in and the flag change I made manually to switch from single site to multisite. If it does I would like to know before I switch so I can igure out what I did to get multisite to work and can duplicate it again.

    HI, I have a similiar problem. Someone else did the upgrade, but did not do a back-up first, here is the message I am getting,
    Fatal error: Class ‘ftlink’ not found in /home/onlineps/public_html/wp-content/themes/psychic_advisors/footer.php on line 15

    She tried other themes, but that did not work, my site is https://www.onlinepsychicadvisors.com

    Do you have any suggestions? Thank you so much for any help at all.

    You problem seems different from my original issue. You should probably start a new support topic so others can help you resolve this issue. My best, unqualified, guess is that you have a problem with some code in the footer of your site. However, there are other people on this forum that are much better at troubleshooting WP than me. A new support topic would get their attention for your problem.
