404 and other serious errors

nightyard – sorry to hear you’re having problems! Can you let us know the version of PHP and WordPress you’re using?

nightyard – any updates on PHP and WP versions?

Also, what version of DecisionTree (DT) are you using? I’m researching your headers already sent by (output started at /home/iasservicesorg/public_html/wp-content/plugins/sidecar-decision-tree/DecisionTree.php:407) error and line 407 doesn’t make sense to me ?? Getting a bit technical, in DT 1.1 line 407 is:

405      /**
406      * Runs on change to the i donated setting
407      */
408     static function on_update_idonated($new_val, $old_val){
409         if($new_val=='1'){

I actually went back and checked other versions and saw similarly unlikely candidates.

But, let’s assume that the error is true, but the line numbers are off! So, let’s try this: can you edit DecisionTree.php file and find the end of the file:

add_action( 'admin_notices', array( 'DecisionTree', 'admin_page_notice' ));

?>

And remove the few two lines so it looks like this:

add_action( 'admin_notices', array( 'DecisionTree', 'admin_page_notice' ));

Technically there’s a trailing return there on the last line. We can remove the ?> which is valid PHP and should remove any output that our plugin might be causing

Hi,
I am 99% sure that the problems are occuring because of my htaccess.

I think a plugin has affected the htaccess as I no one who has access to it says they’ve modified it.

when I try to edit any page it just redirects me to the home page.

I have just tried to use a basic htaccess without all those conditions and it still redirects me to the homepage when I try to edit or view any page from the back end.

The front end navigation works fine though….

I have already tried deactivating all plugins and still occurs.

Update:

a did a CHMOD to change file permissions and thats fixed my 404 errors but i am still getting the same errors as I previously mentioned with the plugin

I tried deleting the last final lines and still this is the error I receive.

Also when I try to add the shortcode of a decision tree to a page, nothing appears.

Warning: Missing argument 2 for DecisionTree::on_update_idonated() in /home/iasservicesorg/public_html/wp-content/plugins/sidecar-decision-tree/DecisionTree.php on line 407

Warning: Cannot modify header information – headers already sent by (output started at /home/iasservicesorg/public_html/wp-content/plugins/sidecar-decision-tree/DecisionTree.php:407) in /home/iasservicesorg/public_html/wordpress/wp-includes/pluggable.php on line 1196

Tablepress shortcode works just fine though so it isnt that shortcodes are not working.

I have also tried a fresh install and I have also updated to the latest wordpress version.

could the issue lie within the fact that the plugins folder is located in /public_html/wp-content/plugins

and the wordpress admin,contents,includes folder and everything else is located in /public_html/wordpress/

the /public_html/wordpress/contents/plugins is empty

all the plugins that are currently installed work just fine and I only just installed tablepress and that worked just fine also.

getting the error on other plugins also

Warning: Cannot modify header information – headers already sent by (output started at /home/iasservicesorg/public_html/wordpress/wp-admin/includes/template.php:1935) in

what could this be?!?!

nightyard – if you disable our plugin do these problems persist?

Yes, the problem persists.

I really do need some help with resolving the issue though.

I get cannot modify header information on multiple plugins when making some changes.

nightyard – If you disable our plugin and the problem persists, then the problem is not with our plugin, but with something endemic to your site. I would try disabling plugins one by one and see if one of them is causing the problem.

As we can only support our plugin, I’m going to mark this ticket resolved. Best of luck in fixing your site!

Marking resolved.
