Module Task-list in Blank

[Aespejo]

I have a problem with this modules after I was spending from the professional version 4.2 to the open source 4.2, update to the version 4.2.1, after which I updated to 4.5 everything again perfect, but on having spent of 4.5I to 5.1, there goes correctly except the list of tasks that appears in blank, once in the version 5.1 of sugar I updated again to the version 5.2 but the problem in tasks was persisting, all these updates have been carried out by the necessary changes in the database. I have tried to replace the module tasks with one of the clean installation of sugar crm os 5.2 but not at all, it differentiates them I believe that it takes root in that the table tasks is different from the one that it would have installing the clean sugar version you 5.2 if someone has idea if it is for this motive that he comments to me on it or if a hand can throw me perfectly.

Have a look at the tail of the files sugarcrm.log (in the root of the sugarcrm system) and error_log of the apache.
Hopefully you will find any error message regarding the issue.
