Warning Errors

  • I am fairly new to wp and have been tasked with updating and maintaining my company’s preexisting website. Whenever I log into my account, I am shown a variety of Warning messages. I am unsure how to fix any of them, so any help would be greatly appreciated.

    The warnings are listed below:

    Warning: Declaration of Axiom_Plugin_Updater::download_package($package) should be compatible with WP_Upgrader::download_package($package, $check_signatures = false) in /home/tporter1/public_html/wp-content/plugins/masterslider/admin/includes/classes/class-axiom-plugin-updater.php on line 29

    Warning: session_start(): Cannot start session when headers already sent in /home/tporter1/public_html/wp-content/plugins/visual-products-configurator-for-woocommerce/admin/class-vpc-admin.php on line 125

    Warning: preg_match_all(): Compilation failed: invalid range in character class at offset 11 in /home/tporter1/public_html/wp-content/plugins/js_composer_theme/include/autoload/hook-vc-grid.php on line 162

    I recommend asking at https://www.ads-software.com/support/plugin/master-slider/#new-post so the plugin’s developers and support community can help you with this.

    Greetings and Welcome

    Unfortunately you have been presented with errors that will take some digging, troubleshooting and time to resolve. This could require doing a lot of hands-on investigating.

    Yes, you could continue to ask questions at this Forum although the answers might confuse you more. Someone, like me for example, could say to Disable all Plugins and see if the error msgs. go away. If they do then Active the Plugins one at time until you get an error msg. Then Disable the one just Enabled and continue this process until all Plugins have been checked. Once the trouble Plugins are known you decide what to do–remove them or figure out what the problem is with them. Do they need updating, is there a conflict with another Plugin, etc.

    If you don’t know how to do these things already, you will need to learn as Adding / Removing / Troubleshooting Plugins is a requirement to using WordPress. There are other things you need to start learning about as well, on your own, as Replies in this Forum might be over a longer period of time than you would prefer.

    If the front-side is currently working correctly it will give you some time to find
    someone who can help. Or you can do the Reply – Answer method for as long as it takes. Most people do the latter although they are not usually thrown into a situation such as yours.
