ioncube interfere?

I installed ioncube for another piece of software i needed to run on my hosting account and needed to add lines in php.ini to make it work.

I did and it worked, however suddenly wordpress updates failed, plugins, themes, etc etc.

Contact my host and they said comment out the lines for ioncube loaders which made the other software no longer run but low and behold, wordpress updates work again.

Now i cant afford another hosting account for the other software, so thats not an option. However, just enabling ioncube on my website shouldn’t break wordpress updates correct?

Doesn’t seem right but who knows…..
