Hi,

First have a look at the log file.
It should always be the reflex 👿

I suggest you to look for max_input_vars in the forum and in the prerequisites.
It is the most common issue on this screen.

in log files:

on file '/var/www/projeqtor/tool/saveImputation.php' at line (84)
2015-04-27 17:39:11 ** ERROR ** cause = Error - Maybe max_input_vars is too small in php.ini

Exactly as I suggested : max_input_vars is too small.
You have to change it in the php.ini (set value to 4000 as advices on prerequisites : http://www.projeqtor.org/en/product-en/technical-en/64-setup-en/412-product-prerequisites-en)

is it reset sometimes or could ful again with 4000 ?

is it on etc/php5/apache2/php.ini ???

is it on etc/php5/apache2/php.ini ???

Yes.

And don't forget to restat php (or apache) to take change into account B)

I have change the value of max input to 4000,
on etc/php5/apache2/php.ini
but it is not work 🙁

i did, i, terminal:
sudo /etc/init.d/apache2 stop

and

sudo /etc/init.d/apache2 start

and it do not work, what's problem 🙁 🙁

this is what I have on the log file:

Your parameter is not taken into account.
Maybe it is not the good php.ini.

Also notice that GD library is not installed : you'll not be able to display charts in reports.

so I have an other PHP.ini ?

I'm so sorry but it was the good php.ini .... :whistle:

It's just that I don't remove the ";" before de variable input_max ....

so now it's works

but how I can install the GD library ?

but how I can install the GD library ?

apt-get install php5-gd

should do the job.

thks you so much, all is good now ...
