Problems after upgrate magento 2.2.5 to 2.3.0

Question

After I upgraded Mageto 2.2.5 to 2.3.0 I've run all the commands in the console (upgrade,deploy,compile,flush), but on frontend it doesn't load the page and in system.log

I'm getting following error

"main.INFO: Broken reference: the 'theme.active.editor' element cannot be added as child to 'after.body.start', because the latter doesn't exist [] [] main.INFO: Broken reference: the 'logger' element cannot be added as child to 'after.body.start', because the latter doesn't exist [] []"

And in backend i have the error :ERR_TOO_MANY_REDIRECTS

Thank you for any advice

Answer 1

The issue in our layout.

First, on the layout, you have a section name theme.active.editor .

ERR_TOO_MANY_REDIRECTS happen for cookie setting issue at magento.Please check the cookie setting at core_config_data table.

Run below query:

select * from core_config_data where value like '%cookie%'

I guess that on your database, your cookie domain is live domain. So, you have to delete that record. and then Flush All the cache.

Answer 2

First, run the below command:

SELECT * FROM `core_config_data` WHERE `path` LIKE '%base_url%'

Next, if the value is enabled SSL then fix to HTTPS and if it is disabled, please edit to HTTP.

Finally, clear cache.

Please let me know if it works!
