Extremely slow backoffice

Question

I have recently updated my prestashop to 1.6, and since then, I'm experiencing performance issues. I have activated error messages in order to check if everything was ok and I found some messages telling me the following:

Notice on line 1279 en archivo /var/www/vhosts/vallesonline.es/httpdocs/modules/inixframe/InixModule.php
[8] Undefined property: stdClass::$dist_chanel

Notice on line 1280 en archivo /var/www/vhosts/vallesonline.es/httpdocs/modules/inixframe/InixModule.php
[8] Undefined property: stdClass::$dist_chanel

The lines 1279 and 1280 are the author and dist_chanel ones:

$module_data = array(
'name'=> $module->name,
'version'=> $module->version,
'author'=>$module->dist_chanel,
'dist_chanel'=> $module->dist_chanel,
);

It is evident that there is some problem with some modules that do not have dist_chanel property, so I check if the module has it or not in order to bypass the problem. If the var is not defined, I set author and diet_channel to ''.

Then, at the end of my log file I found the following:

Notice on line 1957 en archivo /var/www/vhosts/vallesonline.es/httpdocs/classes/Tools.php
[8] Array to string conversion

The line is the following:

curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data);

In which post_data contains the data created on InixModule.php (the var module_data).

I think this problem is causing the performance issues on my prestashop and that has something to do with the update (which I did using 1-click-update).

Any help would be greatly appreciated.

Answer 1

I had same error message. My solution is uninstalling module named "Presta Apps Dashboard" developed by InixFrame. Solved till now.

Answer 2

Do a chmod -R 774 to /var/www/html/prestashop/config/xml/ if you have different users for both owner and group.

Or chown (change ownership) of /var/www/html/prestashop/config/xml/*.xml to www-data:www-data or apache2:apache2 depending on Debian/Ubuntu or Redhat/CentOS - that might help, it might be just permission issue if you check on apache's error log.

The next thing should be just some tweaking on Smarty under Performance to cache all stuffs.
