  • Hi guys.

    since the latest update to 4.3.1 i get only this error, when i try to go to /wp-admin:
    Notice: The called constructor method for WP_Widget is deprecated since version 4.3.0! Use

    __construct()

    instead. in /mnt/web9/e3/24/53702424/htdocs/WordPress_04/wp-includes/functions.php on line 3457 Warning: Cannot modify header information – headers already sent by (output started at /mnt/web9/e3/24/53702424/htdocs/WordPress_04/wp-includes/functions.php:3457) in /mnt/web9/e3/24/53702424/htdocs/WordPress_04/wp-includes/pluggable.php on line 1207

    and if i go to the frontend of the page i have this error on top of everything:

  • This most likely indicates that a plugin or theme needs updating by the developers (or maybe you haven’t updated lately). Go to this page and scroll to the ‘Known Issues’ section, and there you’ll see ‘WP_Widget Error’.

    Hi Bill. thanks for your fast reply.
    i already tried the thing with renaming the plugins-folder … no difference
    now i tried that with the debug mode setting to false, that didnt work either. If it would have worked, i think it just wouldn’t give me the error-message but the admin-panel still wouldn’t be accessable.

    maybe something else i can try?

    best regards, Jan

    Did you try renaming the folder of your current theme as well? Because that may be the issue and not a plugin. Renaming it will disable the theme, and WP will use the default theme found in wp-contents/themes/ (probably Twenty Fifteen).

    ouh yeah. That works! now i can access the admin panel again.
    if i go to “Themes” it shows the theme … just blank.

    so now i update or reinstall the theme or how i get it to normal again?

    best, Jan

    Yes, if the theme has an update, do it. If not, contact the theme developer through whatever support channel is available for it.
