did you uninstall the newsfeed plugin for some reason ?

What version of php are you using?

Did you deactivate a plugin via the DB ?

Do you have dev mode and debug mode set to true at the same time, you cant do that.. one or the other

My answers

No, I did not uninstal the newsfeed plugin.

PHP version 7.0.

Yes, I deactivated newsfeed plugin via DB. If plugin is active there is this error

The dev mode is setted to true and this errors displays if I try to login as admin via mysite.com/sign-in because I setted the site under maintennance.

ok thats the first problem, you cant just deactivate a plugin via the plugin table, there is more that happens during deactivate than just changing the flag in the plugin table. 

So i assumed you set it back to 1, that will fix that issue.

As for the new error you posted in the previous reply:

First check your mod_security to be sure strict configurations are off as per oxwall requirements.  If that does not solve the issue then the issue can be solved in two ways:

1. dont use mariaDB as it requires single quotes in code where non MariaDB does not.

2. locate the lines of code where the single quotes are required and add them.

I can give you Cpanel details to check it.

no thats ok, i dont like going into someones server unless it really necessary.  

Try this - untested and might not work... but try it

open up  ow_plugins/newsfeed/controllers/ajax.php

on line 155 change  'uid'  to "uid"      (use double quotes instead of single quotes)

if that errors out

then try "'uid'"        doublequote singlequote uid  singlequote doublequote

if that fails then set it back to  'uid'   and let me know, ill dig deeper and may need your cpanel at that time.

to clarify just change the 'uid'   NOT the $content['uid'] <--- leave this alone

Hi dave, the site works now. Dont know what happen; 2 hours after I made 'uid' changes site appears back to life. Maybe there is a cron job or ... .

Thank you very much for your help.

Kind regards.
