Hello, I have this error when  I want to get into modules:

[PrestaShop] Fatal error in module Module.php(1080) : eval()'d :
Can't use method return value in write context

What can I do? I I made a change in module.php and it showed me that result:

string(12) "gamification" string(9) "smartsupp" string(8) "gadwords" string(16) "oneandonehosting" string(12) "easywebtoapp" string(8) "cronjobs" string(8) "worldcoo" string(7) "mailjet" string(10) "veplatform" string(9) "graphnvd3" string(11) "addshoppers" string(12) "authorizeaim" string(11) "autoupgrade" string(8) "bankwire" string(15) "blockcategories" string(12) "blockcontact" string(17) "blockcontactinfos" string(16) "blockreinsurance" string(12) "blocksharefb" string(11) "blocksocial" string(12) "blocktopmenu" string(6) "browsi" string(9) "cartsguru" string(14) "cashondelivery" string(6) "cheque" string(8) "cronjobs" string(8) "dpdgroup" string(8) "gadwords" string(12) "gamification" string(10) "ganalytics" string(5) "hipay" string(11) "importerosc" [PrestaShop] Fatal error in module Module.php(1080) : eval()'d :

Next I don`t know what to do! I have Prestashop 1.5.6.1

Thanks!
