It seems you are facing the max_input_vars issue.
Search for "max_input_vars" for hints : you'll have to increase this value in php.ini.

Hi,

Thanks for your answer.

We 've already increased "max_input_vars" to 4000 when we started working with Projeqtor.
We increased value to 5000 and reload Apache but problem still happens 🙁

It's strange and annoying because it works well for others resources !

Maybe your php also uses suhosin module, you you should also change values for it :

max_input_vars = 4000
suhosin.post.max_vars = 4000
suhosin.request.max_vars =4000

We installed suhosin, updated parameters but problem still hapens...

Hi,

Can you check for error in browser console ?

If not error appears, please try and reproduce and wait several minutes, to be sure you got response from server.
Then check again log file.

You should have either an error in the log or in the browser console.

Console screenshot attached.

Thanks.

Error 500 : it means you have some serious PHP error.
You should find error in the PHP or Apache Log file.

Hi,

Bellow Apache log files

You're in Timeout !

Try and extend max_execution_time in php.ini.
Your value is 30, replace it with 300 (5 mn), just to see if it fixes the issue

But it is not normal it is so long.
Maybe you have issue with database connection.
For instance, if you are on Windows with local database, try and replace dbHost from "localhost" to "127.0.0.1" (this solves a DNS issue with MySql on Windows)

After updated timeout, record was registered with correct time response.
We replace max_execution_time on again with 30 and all is ok !

Very odd but ok !

Thanks. 🙂
