You must go to Admin > System > Global Configuration, open tab “Server”, and set “Development” for option “Error Reporting”, so you can see details error in front-end. Based on error message, please send it to me so I can identify your problem. Thank you!

Hi,
I solved all my problems during update our Joomla! website via this post, thank you!
Glad to help!
Hello,
I wanted to briefly explain how my template now runs with Joomla 3.8.
The checklist did not help me.
After updating from Joomla 3.7.5 to 3.8 I had a blank page in the online operation in the frontend. The backend worked normally.
Offline under XAMPP I had in the frontend the message:
Serialization of ‘SimpleXMLElement’ is not allowed
I then made the following change:
… / libraries / src / cache / Controller / CallbackController.php
the code in line 188:
// $ this-> cache-> store (serialize ($ data), $ id);
Now it’s working
Best regards
Fred.
Thank you very much for your bug report and solution how to fix.
I have alsofollowed checklist end up with a blank aministrator backend? What now.. Can’t update anything if I can’t get into backend??!!
Do I need to reinstall backup and just wait for another update that fixes this issue?
I don’t suggest updating to Joomla 3.8 yet this my second site backend that has failed.
Sorry missed it first time through as I never had any specific error message just a blank page but the rename to “mod_sppagebuilder_admin_menu2” has worked for me too thanks guys!
Error: 1054 Unknown column ‘a.client_id’ in ‘where clause’ in BACKEND.
and in Frontend is working properly.
I update it to Joomla 3.8.1….I tried to rename the Folder to “mod_sppagebuilder_admin_menu2” still doesnt work. I hope you can help me. Thank you Admin.
Just search keyword “JAdminCssMenu” in blog post and solve it. Thank you!
Hello guys,
if you have the same problem which I had:
Step 1: This is problem with SP Page Builder admin menu module, you can fix it by temporary by go to this directory [joomla-root]/administrator/modules/, and rename folder “mod_sppagebuilder_admin_menu” to “mod_sppagebuilder_admin_menu2”. (LTheme Admin post)
Step 2: Login as Admin
Step 3: Just make a database Repair: /administrator/index.php?option=com_installer&task=database.fix
Now, Backend works and shows properly with Joomla 3.8.1
It works in my Website and I hope to help you in this matter.
Regards,
C. Antony

Hi,
By unzip download package, you can see documentation file, just open it by double click and see details how to install and custom theme.
/administrator/modules/mod_sppagebuilder_admin_menu/tmpl/default_enabled.php on line 16 i fixed by renaming directory [joomla-root]/administrator/modules/, and rename folder “mod_sppagebuilder_admin_menu” to “mod_sppagebuilder_admin_menu2
Thank you guys.

Ciao,
risolto rinominando la cartella. OK …. Ma è possibile trasformare l’area backend in lingua italiana ? Provo a installare e mi appare: “Warning The update table is not up to date. Please rebuild your update server table”
Thanks for your info. Please go to link https://community.joomla.org/translations/joomla-3-translations.html
Find Italian package and download it, then install it via Admin > Extension > Manage > Install.
interesante articulo. yo tengo el siguiente problema con Helix 3 en el menu.php
Warning: count(): Parameter must be an array or an object that implements Countable in
plugins/system/helix3/core/classes/menu.php on line 239
This is just error, just notice with PHP version, just go to Admin > System > Global Configuration, open tab “Server” and set “None” for option “Error Reporting”.
