I suggest enabling product(s) 1 by 1. Once the error occurs, you will need to look into the problematic product/plugin -- most cases you can see if a similar bug has been previously posted on the product/plugin thread.
STEP-BY-STEP- Enable the Plugin System
- Now go into the PLUGIN SYSTEM/ MANAGE PRODUCTS and disable all products
- Now go into PLUGIN SYSTEM/ PLUGIN MANAGER and make sure all plugins are disabled
- Confirm that profile page is working
- if so, go back into the PLUGIN SYSTEM/ MANAGE PRODUCTS and enable products 1 by 1 (NOTE: after you enable a product confirm that the profile page is still viewable)
- if not, this is your problematic product
- you can either uninstall product OR
- you can post your problem in product thread OR
- you can hire someone to fix the problem for you
- If you have not encountered any problems while enabling your installed PRODUCTS.
- Go into the PLUGIN SYSTEM / PLUGIN MANAGER and enable plugins that are currently disabled. Do this 1 by 1 and confirm that profile page is still working. Keep this up until you run into the problem.
- Once you find the problematic plugin--post your problem on plugin thread.
This is all I can offer you ... anything else will be wasting your time as well as mine.
Good luck!
