Cordial Saludo, espero que alguien pueda ayudarme. He realizado la actualización de prestashop usando el módulo de "Actualización con un Click" de prestashop, desde la versión 1.4 hasta la 1.7, arreglando todo tipo de errores posibles en cuanto a bases de datos, ya que al parecer no transforma bien los esquemas de las tablas y sino es por otros errores. Hoy quiero pedirles ayuda, para terminar mi labor de actualización, si alguien conoce como solucionar este error cuando intento ingresar a algunas opciones de configuración (ejemplo: "http://mitienda.com/adminsen/index.php/configure/shop/seo-urls/" ) : Warning: unserialize() expects parameter 1 to be string, array given Symfony\Component\Debug\Exception\ ContextErrorException in vendor\symfony\symfony\src\Symfony\Component\Security\Core\Authentication\Token\AbstractToken.php (line 155) /** * {@inheritdoc} */ public function unserialize($serialized) { list($this->user, $this->authenticated, $this->roles, $this->attributes) = unserialize($serialized); } /** * Returns the token attributes. * Parece un error de módulos o de permisos en ellos, he intentado corregirlo colocando los modulos como inactivos, el algunas ocasiones o para algunas opciones funciona en otras no. Si alguien sabe como solucionarlo le agradezco el aporte.

Hi prestashopers. I write a module in which I save information in a complex form - serialized. The display of such information is illegible and unedited, which is why I want to display the input form. I just wanted to insert a value: public function renderForm() { $ unserializedArray = unserialize (AdParameters :: getParametersValue (Tools :: getValue ('id_ad_parameters'))); $ Result = ''; foreach ($ unserializedArray as $ key => $ row) { foreach ($ row as $ element) { $ Result. = '['. $ Element. ']'; } if (isset ($ unserializedArray [$ key + 1])) $ MyValue. = "\ R \ n"; } $ helper-> fields_value ['parameters_value'] = $ MyValue; ................ Form return parent::renderForm(); } AdParameters :: getParametersValue() is function quering DB When I list MyValue everythink is ok but in my list is not ok. However, it does not change the value. I need to replace it in the table and when editing in the form. Can anyone help me with this? Please. if you need a broader explanation, let me know, I'll send them.

Sometimes i get this error massage in my prestashop 1.5.6 Notice: unserialize() [function.unserialize]: Unexpected end of serialized data in ...../public_html/classes/cache/CacheFs.php on line 40 In here is my cachefs.php file (line 40 red mark): Any one can solve this? Thanks
